*Help* buffers do have faces, and you can customize them to use
non-default colors.

Beyond that, it is not clear what behavior you are asking for.  How
will the "specified lines" be specified, and by whom?

Doc strings are general Emacs feature, so if it's desirable to have
specific parts of them highlighted in certain ways, the first question
to ask is which parts will those be, and how will they be identified?
