Depends on the state. Texas allows overpayments to be requested from the person who received them although they knew they were not owed. If not, you can sue them. Check you state laws.
No, if it is an overpayment, than it's a gift. However, support does not stop until age 22 in some states. see links below
Contact your State's child support agency. They can take various actions to establish/collect support. Be patient but persistent. Good luck!
Yes, however it should be adjusted to an amount based on the Worker's Comp payment. This can be done through a joint request to child support enforcement, or you can wait for him to go to court, however it will be retroactive and the overpayment deducted from future payments.
Child support for illegal children can be difficult. A court order is required to enforce child support payments, and this depends on the parent being a legal immigrant with a legal job to collect from. If a illegal child is born of a US citizen or naturalization, the child is no longer considered illegal.
If you are their legal guardian, you can collect child support from both parents of the child. If you are not their legal guardian and they just live with you, you do not have rights to child support.

generally is not done. see links
no, as that would create an overpayment.
Generally, you can address that issue in the court that has jurisdiction over your case. You should be able to file a petition for modification of the child support order until the overpayment has been properly applied to your child support obligations. You can ask the court about sanctions against the recipient.

If your child is not living with you, you are not eligible to collect child support. The child support should go to whomever is caring for the child.
Your custodial parent can collect unpaid support that accrued under an order. Support sometimes continues after the child becomes an adult if the child is disabled.
yes
Public assistance recipients assign their rights to child support to the State which, presumably, will attempt to establish/collect support.
Reference to "seventy four percent" is unclear, but it seems unlikely that the child's mother could collect current child support in such a situation. (She can still collect past-due support, if any.)
No, child support can only be taken from the birth parents.
To my knowledge, felons are not prohibited from collecting child support.
