It needs to have max Happiness AND you need to have the National Dex.

Provided you have the national Pokedex. Yes.
evolves at level 22 and evolves to crobat with friendship it evoles into "golbat" at level twenty two. Golbatwill evolve into by being really happy.
It won't evolve because you don't have the National Pokedex. Once you have the National Pokedex, which you get after beating the Elite 4, catching 60 different species of Pokemon, and completing the Sevii Islands sidequest, you'll be able to evolve your Golbat.
Golbat does not evolve at any specific level. You need to get the Golbat to like you a lot and then when it levels up it should evolve into Crobat.
Golbat doesnt evolve by level, you have to trade it for it to turn into Crobat.
