She could either be flirting or just giving you a nickname.
"Chick" is slang for woman or girl. It doesn't "mean" anything.
Either that or he's very fond of you.
To be batty is to have "bats in the belfry" -- this means you're silly or crazy.
he means that he likes that girl alot
I'd say move on to another boy. Judging by what you provided in your Q, this boy wants to play and have his fun. Don't waste your time.
Though there is no sure way to tell, it probably does mean that. To be sure, try listening to the tone in his voice.
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!
