Asking for a raise.....for a coworker
I don't know why but one of my coworkers says they need to make more money but is afraid to ask for personal reasons, so they asked me to ask our boss for them. I don't feel comfortable negotiating for someone else, but he's also my friend and I would feel bad if I didn't help.

I agree with the other posters. This is not appropriate, probably not very effective, and in some situations could actually reduce the chance that he'd get the raise. (As in all situations, there are exceptions. For example, if you are a supervisor of some of his responsibilities, and part of your official role is to report on his work effectiveness, you could lobby for a raise.)
You could help in other ways. For instance, you could role-play with your friend. Help him practice what he could say when he goes and asks for a raise. If your company has peer reviews, you can point out the good work he has done. And even if there is no formal peer review process, you could compliment something he's done well to your boss.

ya I agree, that puts you in a tough spot with nothing to gain from it.

Even if he is your friend, you can say that is not your business and you just don't feel right doing that

That is absolutely out of line! First of all, never talk money with coworkers, even if they are friends. Very innappropriate
Don't ask your boss for a raise for your coworker. Bad move if your coworker comes to work on time and do what he or she surpose to in the work place the work would be regoniz and boss would tell them they doing a good job
