Go ask the person who's mad at your friend whats wrong. Try to get them to go in one room and conflict them. See what's wrong.
You can help your friend by first just loving on them, next you can go over the problem with them. If it a really serious issue you should bring it to someone who can help.
You can help them by speaking to them, talk about their feelings, say there is nothing to worry about because you'll be by their side all the way..
Give advice. Take you somewhere that they know will make you happy. Give you gifts. Try to fix your problem for you.
