I like snap loan, but really it's the least bad. It is distinctive and yet not ambiguous. EasyLoan/QuickLoan/ActiveLoan is just too jargony. Everyone uses those terms in every product. I don't mind names without loan in them, but the ones you have listed are terrible. Avoid at all costs. That leaves SnapLoan, the least bad. Somewhat less jargony, a bit catchy, though not much, and probably more unique than the others.
