Yes you can pay bills at the money store area
Yes
Some, but I've never done it. So I've no clue of which ones, cost, or when they will post on your account.
I think you can, though I have yet to see any Bills working as a cashier. I know I have paid a Veronica, a Sharon, and a Beth. You could always call and ask if "Bill" is working.
Yes, but call first, for payment center hours.
