So if a parent has to be present for ear piercing, can It be a adult family member instead?

You would have to be the registered parent or Guardian not just any family member that's of age. That's not saying that tattoo parlors would not allow it it's just not to the letter of the law and would leave the tattoo parlor White open retaliation from parents and open the lawsuits and potentially losing their license.

U have to have the same past name as childs birth certificate.and parents id.

I'm not sure, I would call to be sure.
