It is slang or gangsta for kid or buddy.
When a boy calls you names, there is more than one possibility of what it could mean: 1. The boy who calls you names might like you. When a boy likes you, they might tease you in a joking way. 2. The boy who calls you names might think you're annoying, so he calls you names. 3. The boy might be mean, and call everyone names.
it means he likes you
Because he ethier fancies you (most likely) or wants to be really good friends with you (possibly)
He means that he thinks your pretty. Idiot.

if it is a boy then they are flirting. if it is a friend then it is a nickname
it means that you are a show off
If another boy calls another boy's name a lot then it means that he is getting fond of the other boy.

Yunhanam doesn't have a literal translation, but it's a term of endearment. An older girl calls a younger boy this. The best example I can give is SHINee's 'Yunhanam'. Hope this helps!
