Unless the lender secured your loan to your assets, the lender's recourse is to sue you and try to collect. Meanwhile the interest owed on the loan will mount. But, if you can't pay, then there's little that the lender can do.
You can try to negotiate with the lender for a lower interest rate and payment plan. But, if the lender doesn't want to negotiate, then you may have to declare bankruptcy at some point in the future to get rid of the debt.
The existence of multiple loans certainly will affect the lenders ability to collect. But, because the individual amounts are relatively small, the lenders will almost certainly take you to small claims and get a judgment, and then try to collect.
They probably won't be successful, but the cost of a small claims action is minimal, so the risk is small for the lender.
