Answer 1

Have you seen https://www.gnu.org/software/auctex/manual/auctex/Faces.html?

M-x customize-group RET font-latex-highlighting-faces RET

Answer 2

There is a general way to change any font you see in Emacs. Move point to the text in question and hit C-u C-x =. You will get a *Help* buffer with something like:

There are text properties here:
  face                 font-lock-variable-name-face

The face name is a link that you can open. This gives you a description of the face, with the first line being:

Face: font-lock-variable-name-face (sample) (customize this face)

customize this face is a link that takes you to the appropriate Customize buffer.
