Not necessarily, but if he asks you out or something, then definitely.
Likely that he's a nice person.
he looks at you a lot and he smiles at you.
if hes barely talked to you before, he may like you
Either he is trying to get your attention or he wants to beat the crap out of someone.
No, it doesn't mean he loves you. It could mean he is interested in you, or he could simply be nice and smile.
sometimes but others they might just be friendly!
