Minors are not responsible for those decisions. The custodial parent is responsible and is the one who will be held accountable by the court.
The children don't get to decide that they can disobey a custody agreement at any age.

The most likely scenario is that the children will live with the other parent as long as that parent was not deemed unfit while the custodial parent was alive. If that parent was denied custody for cause the courts may consider another gaurdian should the non custodial parent still be considered unsuitable.
No. Support is based upon the income of the non custodial parent and in some cases the needs of the minor child/children.
A child can make that decision at the age of 18.

Maybe, if the absent parent does not share custody in any manner and there is not a visitation order in place, a custodial parent can take whatever action he or she chooses in regards to a minor child. However, courts do not look favorably upon any parent who does not allow the other parent to have a relationship with his or her minor child/children unless there is substantiated reasons (child abuse, endangerment, etc.) for the action. A parent who is being denied access to his or her child/children can file suit for visitation and/or custodial rights if they so choose.
It depends where you live and what the Family Laws has to say about it, better consult your Lawyer.
An minor can't decide to not see a non-custodial parent -- if there's a court order, it will continue until the minor is of age, 18.
