Is there art stores around there?

I think you are trying to say are there art stores. If that's the case, then yes. There are at 4 or 5 surrounding the perimeter of the park.

there are only a few stores of art supplies near by central park

Yes there's is I can't remember off the top of my head but they are about 5 blocks away on 8th ave I believe

Yes

All kinds of them anything you're looking for it surrounds the park sometimes they're in the park
