Yes. They are still the child's parent and responsible for supporting their child.
no
Yes, it can. Moving in with the other parent is grounds for "flipping" child support payments. However, this must be done by court order.
No. Your obligation to support your own child takes priority over any subsequent support you offer for another person's child. The court would not decrease your child support obligation for that reason.
Child support in Ohio usually continues until the child is 18, and up to the age of 21 if the child is in school. Whether or not you have to pay child support if the child is living with the noncustodial parent depends on the support order that it is in place Typically you can expect that you will have to expect to pay support.
i am a custodial parent in Michigan. I've been to court to fight it, but unfortunately it is law that if the noncustodial parent is incarcerated they do not owe child support for the time that they are locked up. but if they owe back child support then you can seize anything they own.
