No, legally a minor has no choice in the matter.
The guidelines are basically the same in every state but obviously there are a few minor differences. Joint custody consists of Primary Custody & Secondary Custody. The parent with primary custody is who the child lives with & the other parent has secondary custody. Depending on the age of the child & the state in which they reside, the court may let them determine where they choose to live. Or if both parents agree on the child's decision then the child can live with either parent.
If you have joint custody, there is one parent that is the custodial parent. A child can move in with you if you are the custodial parent or you can file in court to change your status to the custodial parent. The child should want to live with you as well.

Not if you are suppose to give the child to the other parent.
yes
When parents share joint custody major decisions concerning the child(ren) must be agreed on by both. This includes moving the child(ren) out of the state jurisdiction where custody was awarded. Either party can petition the court to allow the move or block the move if it becomes a matter of contention. The court will always renders decisions based on the welfare of the child(ren).
Must be since all the people doing it are not in jail
You must return to court to petition for a modification of the custody order. You should seek the advice of an attorney who specializes in custody issues.

Why are there two orders? Which was filed first? Where do the children live?
There are no distance requirements for joint custody.
