I am a Brazilian lawyer. As I am not a lawyer specialized on copyrights, much less the Californian copyright laws, I cannot give reliable legal advice. However, I can help shed some light on this, on top of what @Paul-Stanley wrote.
Copyrights are a type of intellectual property rights, and the design of typefaces per se have some protection or not depending of the jurisdiction. On the other hand, the font files from which the typefaces are generated on computer systems are source code which are later translated to program instructions, which per se are copyrighteable and can be licensed for certain uses and/or users.
Licenses are contracts that bind what you, licensee, can do with what the licensor provides.
The Alladin Free Public License have these terms restricting your use of the fonts:
This license is subject to the following restrictions:
(a) Distribution of the Program or any work based on the Program by a
commercial organization to any third party is prohibited if any payment
is made in connection with such distribution, whether directly (as in
payment for a copy of the Program) or indirectly (as in payment for
some service related to the Program, or payment for some product or
service that includes a copy of the Program "without charge"; these are
only examples, and not an exhaustive enumeration of prohibited
activities). The following methods of distribution involving payment
shall not in and of themselves be a violation of this restriction:
(i) Posting the Program on a public access information storage and
retrieval service for which a fee is received for retrieving
information (such as an on-line service), provided that the fee is
not content-dependent (i.e., the fee would be the same for
retrieving the same volume of information consisting of random
data) and that access to the service and to the Program is
available independent of any other product or service. An example
of a service that does not fall under this section is an on-line
service that is operated by a company and that is only available
to customers of that company. (This is not an exhaustive
(ii) Distributing the Program on removable computer-readable media,
provided that the files containing the Program are reproduced
entirely and verbatim on such media, that all information on such
media be redistributable for non-commercial purposes without
charge, and that such media are distributed by themselves (except
for accompanying documentation) independent of any other product
or service. Examples of such media include CD-ROM, magnetic tape,
and optical storage media. (This is not intended to be an
exhaustive list.) An example of a distribution that does not fall
under this section is a CD-ROM included in a book or magazine.
(This is not an exhaustive enumeration.)
(b) Activities other than copying, distribution and modification of the
Program are not subject to this License and they are outside its scope.
Functional use (running) of the Program is not restricted, and any
output produced through the use of the Program is subject to this
license only if its contents constitute a work based on the Program
(independent of having been made by running the Program).
On (a) we have the restriction of not selling works based on the program, i.e., the font files which are source code compiled to program code interpreted by the computer glyphs renderer (FreeType is one example of a computer glyphs renderer, Windows ClearType is another). This restriction is only in place if the selling is from a commercial organization to anyone else (person, non-profit organization, commercial organization, government, etc.). On (a.i) it says that charging a flat rate from the public to access any random content is allowed, but providing the fonts only for a specific group of individuals is not allowed. On (a.ii) it says that selling computer media such as CDs containing the unmodified fonts is allowed only if all information and programs on that media are not charged commercially, which in my opinion allows for selling a CD with only the AFPL fonts (or with any other software or content which is not charged for) for just the price to cover the CD manufacturing and shipping costs.
But on (b) we have that running the program, which as a font is rendering its glyphs (the letter forms) is not restricted and any output (any text rendered with the font) is not restricted as long as the output contents are not a work based on the program (the fonts).
Well, if you print the letters "a" through "z" and make stickers to sell them, it is a work based on the output of the font. If you print the word "Love" and make cups/shirts/stationery with it printed, it is a work based on the output of the font. If you print a sentence such as "World's greatest mom" on a frame and sell it, it will also be a work based on the output of the font. That is because the shapes of the letters matter more thant its contents, i.e., the content meanings are not meaningful so that they could be copyrighted.
However, if you make a movie and use those fonts on the ending credits, create a book and use the fonts to render the text, the content of the works will not be based on the output of the fonts because one could use any other font and the value of the work would not be changed in any significant way: The fonts are not used to build a commercial product, the fonts are the means to deliver the product.
Please note that this does not allow to create an eBook reader with that font to render texts as that would fall directly on (a): The eBook reader has the font as one of its bases and the payment for the font is indirectly tied to the eBook reader as you are charging for making the eBook capable of rendering texts with the font. This does not fall on (a.i) nor on (a.ii), neither falls on (b) because the font is copied, distributed or transformed inside the eBook reader.
What about eBooks, then? It depends on the ebooks' file format.
PDF files allow for the output of the font to be embedded, so only the letter shapes (the fonts outputs) are stored. The font files per se aren't inside the PDF, only the outputs (the glyphs) and how to position them on the rendered PDF.
Also, it is very dificult, if not impossible, to extract the glyphs from the PDF and recreate the original font: One would have to create a PDF with every glyph combination possible so the kerning pairs, the ligatures, the diacritical marks, all the symbols the font can render, and even then if the font file has optical sizes one would need to do that again for each of the font's optical size. Such a PDF that allowed for font extraction and recreation would not be a creative work independent of the font, but a work based on the font. Even a very extensive text corpus could not have all the glyphs the font can render because of the dingbats and symbols, but then it would be a gray area for the license and definitively unethical use of the (license) contract, which is forbidden by law (at least in Brazil).
ODT, DOCX, DOC, EPUB, HTML+CSS files, on the other hand, don't fall on the (b) exception as they allow for the font file to be distributed together with the eBook's contents, even if the font is subsetted to store only the used glyphs and reduce its file size. The font can also be easily extracted from these eBook types, which reinforces the fact the font is distributed with the work: Distribution of the font means the work (eBook) which has an AFPL licensed font inside of it cannot be sold by an organization, only given for free or sold by a person, because of the (a.ii) terms.
Lastly, we must recall that some formats (such as EPUB and HTML+CSS) allows font linking, i.e., the font may be stored on a public server that allows anyone to retrieve the font, even users reading an eBook with the font linked. Such eBooks with linked fonts may be sold, as this method of using and distributing the font do not fall on any restriction on (a), as one can turn on or turn off the server distributing the AFPL font and the eBook would still be readable, even if not with the intended typeface, and the user of the eBook reader is exerting its right to run the program.
If you embedd the font files inside the eBook, you will not be able to sell the eBook without infringing your license rights if you are an organization. And as long as you use the right eBook format to store only the output of the fonts or link the fonts, you are not restricted in any way to sell your eBook.
