getting storage issues message

the free account allows 500, however, i think i'm around 350.  is this customary to receive warnings at this number, or will my forms be deleted.

also, if i upgrade, it appears that that will allow unlimited form storage.  will it also allow for each form to redirect to outside payment options, or is that part of the 5 payments allowed?

I checked your account and it is under the free account. 

Are you referring to the storage plan which will give you unlimited form storage? If yes, storage plan is still the same as free account limits except with unlimited form storage. The payment submission limit is 10 for free account.

If you're referring to different plans, here's a the pricing page link: https://www.jotform.com/pricing. Also, if you're planning to upgrade account, please follow this guide: https://www.jotform.com/help/331-How-to-Upgrade-My-Account

Hope that helps.
