Are these signs he likes me? Should I make a move?

I pretty much guarantee you that if you make the first move by asking him out, he'll love you forever for it. Nothing is more sexy than a girl asking a guy out, NOTHING. It shows confidence and uniqueness from all the other girls.

From the signs you have given, he likes you.

Here's a tip: When you see him, give him a big smile and say "Hi", as though you're really glad to see him. Just might work wonders!

it sounds like he is into you, but wait to see if he shows anymore signs that he is also if he does show more signs that he is into you..talk to your best friend about it because if he does she might be uncomfortable about so talk to her and see what she thinks about the situation

I think he likes you. But, to be safe you should wait and see what else happens =)

o0o0o... Best friend's brother. Touchy subject. -- Before you go and make your move on this dude who seems like's definitely interested ;) -- make sure it's cool with your friend. Sometimes those situations can make the 'best friend/sister' really uncomfortable, so talk it over with her, see what she thinks. But just strike conversation with him and you should be golden :)

Good Luck!
