OK, first - closing your account is a good thing. You should do that right away. No need to let any of your lenders know you're doing it until after the fact either.

Second, other than FBD/ThinkCash (which is backed by a bank), all of your internet loans are illegal. You are only required to repay the principal amount borrowed (the original amount of your loan). You do NOT have to pay fees, interest, etc. Anything you've paid above and beyond the original deposit amount is an overpayment and you should ask for a refund when you send your illegal lender letters. If you do still owe some principal, tell them you will only pay via money order and that they will need to supply you with a physical address. No address, no payment. I'm assuming this is the breakdown:
Horizon borrowed $300. How many times have you paid them the $90 rollover fee?
USFast Cash borrowed $300. Again, how many rollovers?
Eastside How much was your actual loan? $350? How many times have you paid their fee? ($137.50?) - - I'm guessing here.
United Cash - borrowed $300? How many rollovers?
Cash Adv borrowed $150? How many rollovers?
AdvanceMeToday borrowed $300? How many rollovers?
You can follow the advice

FBD you need to pay. You might try working out an alternate pay schedule with them but you may not need to once you get rid of the others.
Of your TX storefront loans, Advance America, Cash America and EZ Loans are all members of the CFSA. They should allow you to enter an extended payment plan. This will stop all interest from accruing and divide your balance into 3 (or sometimes 4) equal payments. Mo Money isn't a CFSA member but, I would contact their corporate offices and propose that your loans with them be combined and ask for some type of extended payment plan with them as well. They aren't obligated to do this but sometimes will. If they won't, you may still be able to swing paying them off per your original terms since you should have access to some additional money once the others have been dealt with.
Let me know if you have additional questions. I'm happy to help!
