I ain't got no money. You ain't got no money. He, she and it ain't got no money. We and they ain't got no money. Basically, there ain't no money at all.
Of course, "ain't got" means "haven't got" so we also have "ain't" meaning "has not" or "have not". So, you can use it as a past tense in something like, "I ain't been nowhere".
Man, why do these little words have to be so complicated?
