Yes, but you have to file for it in court.
You can not get child support for the previous year if there is a filed court document stating that you agreed not to get any. The best you can do is file for a change so that child support might be able to start, but it would not be retroactive.
Not if an order is already in place. If not, yes in those states where 18 is the age of majority, however you have just one year to do so.
Yes, you can.
Child support accrues from the moment the support order is issued, not from the birth of the child.
You or your parents will pay it. I've seen a $700 average child support payment on a 12 year old by his former sitter. She just waited until the statute of limitations ran out to file for retroactive support all the way back to the birth of the child.
You can request to have your child support lowered due to a change in income at anytime. You will have to file for a review with child support recovery or take the case back to court to get it reduced.

That is dependent on the state. In most states you have until the child reaches the age of majority, than the child has one year longer to file on their own. However, in Ohio you have until the child turns 23 to file for up to 18 years of retroactive support. see links
Uh, no. It wasn't a loan.
no
The parents have to go back to court to file a modification of the custody order. They should also terminate any child support order that obligates the father to pay child support
