Technically the child has no right to decide until reaching the age of majority (18), at which point they're no longer a child.
Only Indiana and Texas have laws setting out a specific age at which a child can make a choice, and even than there are some limitations. With those states, it is age 14. In all other states, the general rule of thumb is that a 12 year old can express and opinion, however the judge is under no legal obligation to consider, or even hear it. In either case, a motion to the court must be filed for a determination to be made.
Once custody has been awarded by a court it would take another court order to change that arrangement. The court may listen to a child's request to change custody but it is under no obligation to modify the custody order at the child's request. The court would be looking for an appropriate reason to order a change in custody such as the custodial parent being unfit and the change being in the best interest of the child.
He has to be 18.
Here the child at 16 years can not decide where she or he wants to live. As they are minors the court will decide it for them.
Depends if the parent has said that the child can choose what he wants, if the parent has then it is recommended that the child is given the choice of the school that they get to go to
No he can not.
In Maryland, legal guardians are responsible for providing support and care for their children until they reach the age of majority, which is 18. If a parent moves out and leaves a 17-year-old without adequate support or care, they may be at risk of being charged with child abandonment or neglect. It's recommended to consult with legal authorities or child protection services for guidance in such situations.

18. But if it goes to court the court might ask the child who he wants to live with if he is around 15yo and the court might follow his wish but is not obligated to.
No she may not - not without the agreement of both parents or the permission of the court with jurisdiction. She can, however, make that decision when she reaches the age of majority where she lives.
No.
Florida don't allow minors to decide which parent to live with.
