A creditor can seek to collect on a debt even if the creditor has charged off the debt or otherwise declared that it was a bad debt. The only way to discharge the debt is for your son to file for Chapter 7 bankruptcy, and wipe out all his previous debts.
Alternatively, your son may be able to negotiate a payment plan with each of the creditors. In the payment plan, your son would pay off the agreed amount over time. But, make sure that the creditors agree in writing that if the payment plan is paid as agreed, the creditor will withdraw any negative credit information from the credit reporting agencies.
Please note that it appears that your son may be judgment proof. That means that the creditors cannot seize any of his property as it all may be exempt under Texas law. For a list of all the property that your son can protect from even a creditor with a judgment, please review my legal guide:

Also, there is a four year statute of limitations for debt collection in Texas. So, if the debts are over four years old, your son would have an affirmative defense.
