Firearm laws vary state by state, so it would depend on which state you are talking about. It depends on where you are and what you mean by "license." In the U.S. in most states, you have to be 21 to get a handgun carry permit. In most states, you do not need a license just to own a gun.
No if the gun is not registered in your name , no you can not own a gun. if you do not have license to own a gun you can not have it either
No.
No it's not necessary.
You don't need a gun license if you are 25 but if your under 25 you do need a gun license

In New Zealand you have to be 18 to own a gun licence.
No.
You need to define the term gun license. In most of the US there is no license to own a gun. Some states require a license to carry a gun. others to carry a gun concealed. There is also a license to make or sell guns. All are different and have different procedures.
To get a gun license you would need to go into a gun store in the town you live in and ask for the information you need.
No, you do not.
