What are signs that girls give to guys that aren't interesting and that are interesting?

They would tell you straight up that they're not interested or avoid you and make fun and insulting remarks about you. For the interested part if the girl and guy are friends the girl would most likely want to spend as much time with the guy, they would probably joke w/the guy a lot, laugh, smile at almost everything the guy is saying, maybe more touching, if they're looking at the lips or eyes when they guy is talking.

They part their legs a little bit.
They follow you, ie they let you lead the way.
They let you kiss them(don't ask)
They orient their body to point at you when your talking.
They mirror your body language or actions
They get upset if you stop talking to them.
They talk trash about whatever girl they see you with or think your interested in.
