No he can not. A step parent have no legal right to the step children. This could only happen if the parents consent to it. A minor can not choose but the court will hear their opinion at 16. They might not follow it though.
Not without a court order saying they can.
16yo can not choose custodial parent at all. The court might listen to your opinion but that is it. And no, step parents do not have any legal right to the child.

A birth father is a genetic father of a child, as opposed to an adoptive father or stepfather.
It could be if they didn't have permission from the adoptive parent.
* Unfortunately, you did not give any reason as to why the birth parent is giving up their young child to a relative. If at all possible; even if it means government assistance the birth parent should try to keep their child. If it's absolutely impossible then all the birth parent can do is try to explain to the child the best they can, but it will never be enough and the child will feel unloved by the birth parent. Eventually the child will grow accustomed to being raised by a relative, but will eventually grow up and want to know why their birth parent did this. The least the birth parent can do is write a heart-felt letter explaining the circumstances as to why they had to give the child up and give the letter to the relative and when the child is old enough to understand and asks 'Why did my birth parent give me up' then they can read the letter. The birth parent should keep in touch with the relative to see how their child is and at some future date and providing the child wants too then the birth parent and child should meet when that child is no longer a minor.

In the US, a parent may choose any name s/he wishes for the child, as long as it's not done for fraudulent purposes.
the parent should be on the birth certificate so long as they are the biological parent. Doesn't matter if they are a US citizen or not.
