Problem with style in biblatex references

Question

So I've been writing my exam in Overleaf Latex (new to Latex) and I'm experienced three kinds of problems. I'll just simply state the problems then show a picture with more details:

First problem: I would like to change my font for all my references to "Times New Roman". (Purple ring)

Second problem: I would like to move the second row and rest of the rows to the red line so it aligns with the first line. (Red arrow)

Third problem: I would like to get rid of the black boxes I guess randomly in my references. (Blue arrow)

As general setup I currently work with:

    \documentclass[draft]{article} 
%but will change this to \documentclass[a4paper,oneside,swedish]{article} once everything is done correctly.

I use:

\usepackage[
backend = biber,
style = authoryear-comp,
citestyle = apa, 
sorting=nyc, 
isbn=true, 
doi=true, 
dashed=false, 
maxbibnames=99,
uniquenames=init,
giveninits 
]{biblatex}

For the first problem I have imported some .tff files for Times New Roman and applied them for a custom font like this (Files are included in the folder "Typsnitt") and they are working in normal text.

\newfontfamily\timesRoman[
    Path                = Typsnitt/,
    Extension           = .ttf,
    BoldItalicFont          = timesbi,
    BoldFont                = timesbd,
    ItalicFont              = timesi,
]{times}

I've also changed title and institution in references with the following:

\DeclareFieldFormat*{title}{\timesRoman\textit{#1}}

\DeclareFieldFormat{institution}{\timesRoman\textit{#1}}

And changing the size of my references with the following:

\renewcommand*{\bibfont}{\parskip=12pt\small}

For the second problem I've tried solutions like:

\setlength{\bibleftmargin}{0mm}
\setlength{\bibindent}{0mm}

But also with a list which I'm a little bit worried that this only work with natbib:

\defbibenvironment{bibliography} 
  {\list{}{%
    \setlength\bibleftmargin=0mm
    \setlength\bibindent=0mm
  }}
  {\endlist}
  {\item}

As for the third problem my worries is that something is wrong with hyperlinks but I'm not sure. Here is my setup for that:

\hypersetup{
    colorlinks = true,
    linkcolor={black!50!black},
    citecolor={black!50!black},
    urlcolor={black!80!black}
}

I have and I've been looking a bit at this but I guess this solution is for natbib only since they use \begin{thebibliography}{0} and \end{thebibliography} and not \printbibliography which I use.

Would be glad if someone have a good input for all this problems Kind regards

EDIT: So sorry if I used multiple questions but I thought I could wrap all my questions in with one picture (which I also forgot to include).

EDIT2: Big thanks to moewe and Skillmon for fixing my problem! First problem was solved with this:

\newcommand*{\bibfont}{\parskip=12pt\normalfont\small}

Second problem solved with this:

\setlength{\bibhang}{0pt}

Third problem solved with this:

\documentclass[a4paper,oneside,swedish]{article}

Answer 1

Just collecting Skillmon's and my comments into an answer, since you mention that the issue is solved.

1. The font settings for the bibliography generated by biblatex are given by

   \newcommand*{\bibfont}{\normalfont\normalsize}
   

   This means that the bibliography will use the default font in the default size.

   If the rest of your document uses a different font this implies that your document does not use the default font settings defined in the preamble.

   Change your font settings so that the document can use the default settings.

2. The hanging indentation of subsequent lines in bibliography items is controlled by \bibhang, if set to 0 there is no hanging indent

   \setlength{\bibhang}{0pt}
   

   Note that in that case you should set \bibitemsep to a larger value so that your readers can tell where an entry ends and the next one starts.

3. As Skillom commented this comes from the draft option passed to the document class. With draft active overfull boxes will be marked with a small black rectangle (a slug) in the margin. See Latex generates pdf with black end of line.

   Fix the overfull and underfull boxes and remove the draft option.
