What does the paperwork state? What are the father's reasons for not wanting to give permission? Will the trip interfer with his visitation and can you offer an alternative visitation schedule in it's place? Also, in my dealing with an Ex, the father may feel "threatened" and should attempt at developing atleast a decent acquaintanceship with the new husband. Weigh out the benefits of the trip, your son's desires, and if you need to go on the trip with them, I would attempt it before taking this back to the court room.
Legally, in most cases, yes. Ethically, no, not without permission.
No, legally he cannot take them with him without your permission.
A minor in the US needs parental permission to marry. Even if the parents of the minor allowed her to marry and she would then be considered emancipated it is unlikely she would be able to apply for a spousal visa for her husband until she is of legal age. If the minor marries outside the US the marriage would be legal. A minor cannot legally leave the US without parental permission and in most cases being accompanied by an adult. A minor who left the US by illegal means and married in a foreign country would not be considered legally married in the US.

Not legally. They have to have parental permission or be emancipated.
Yes, with your parents permission
No, not legally.
If your parents give you permission, you can move out at any time. Giving that permission does not releave them of their responsibilities for you.
Yes, because she has SOLE custody, so you have nothing on the kid legally.
Yes, you can give them permission to move out. It will not remove your responsibility for their welfare.
