I would like to have different font sizes for the buffer windows in Emacs. That is, I would like to have a bigger font in the buffer where i write the code, and a smaller font in the buffer where i use the term to browse and run the scripts. Is it possible ?
Yes, you can use a hook:
(add-hook 'term-mode-hook (lambda () (text-scale-decrease 1)))
C-x C-+(text-scale-adjust) in the given buffer.face-remap-add-relative: emacs.stackexchange.com/a/7283/2287
