Are there simple alternative of these font sizes in ConTeXt? Or one needs to use some special module? I looked at this page here. It seems to be a lot of boilerplate of such a simple task.

You can change the font size for the entire text using \setupbodyfont:
\setupbodyfont [18pt]
If you want to change the font size of a smaller part of the text you can use the following constructs:
{\tfa large}
{\tfb even larger}
{\tfc huge}
Or if you prefer absolute values:
\switchtobodyfont [16pt]
For more details see the ConTeXt wiki - Font switching → Font sizes.
\tfa
,\tfb
,\tfc
, etc. or e.g. with\setupdodyfont[18pt]
. If that doesn't suit your needs please add more details and explain what exactly you want to do.
