if they can find a way to be emancipated (which takes alot of work, and you have to prove you are mature enough to make decisions for yourself) or the simpler way would be to try to convince your parents that it would be better for you in New Jersey. But it is possible.
Yes, Skrillex is adopted. He found out when he was about 16 and that his real parents are really his aunt and uncle and his "parents" are really his uncle and aunt.
What do my parents need to do to let me be adopted by my aunt and uncle at sixteen
Your uncle is the brother of one of your parents or the husband of the sister of one of your parents. Your aunt is the sister of one of your parents or the wife of the brother of one of your parents. You are their niece (if you are a girl) or nephew (if you are a boy).
They had to live with there aunt and uncle because there parents were no longer there to look after them
A niece or nephew is the child of an aunt's or uncle's brother or sister. So the parents of the aunt/uncle and of the niece's/nephew's parents are the same people - their grandparents. The grandmother of the aunt or uncle is the great grandparent of the niece or nephew.
He lived with his aunt and uncle
Your aunt's husband is your uncle. You are his nephew if you are a boy, niece if you are a girl.
If the parents are absent, anyone related to the bride or groom does it instead, usually an older sister/brother or uncle/aunt.
No, cousin and great aunt are very different relationships. Your great aunt is the sister of your grandfather or grandmother. Your first cousin is the child of your aunt or uncle. (Your aunt and uncle are sister and brother of one of your parents.)

An honorary aunt is a close friend of the parents who is called an aunt, though not related by blood. For example, if you have a friend who has a baby, you may be called an aunt (or uncle) by the child and parents even though you're not related.
There is no relation between you, and your biological Uncle's wife's sibling's daughter. Your Uncle's wife is technically an "Aunt in law", though as routine courtesy is simply called "Aunt". Her brother/sister, if your family and her family are that close, could be regarded as an "Uncle/Aunt in law", as a stretch. Thus the daughter of him/her could be thought of as a "cousin in law" to you. But this is all a matter of courtesy, there is no biological or legal relation.
