Provided you are not in violation of the local, state and Federal Laws, yes.
The Second Amendment
21 for hand gun 18 for long gun
Your question is rather vague. If you mean what should a physician do if someone OWNS a gun- I would ask why they should do anything. Owning a gun is not an illness, and is a right guaranteed to Americans. About 1/3rd of he households in the US own at least one gun- and I know several doctors that own guns.

Yes, it is.
There are no exact records, since you do not need a permit to own in gun in most places. It is ESTIMATED that between 1/3 and 1/2 of all households in the US own at least one gun.
Not in the US. Federal law.
In the US, about one third of all the people own a gun, so I would suspect they think it is right. Addendum: I suspect rather more than that think it's right in the sense that they think it's fine for people who want guns to have guns to have them. I don't personally own a gun, but I am generally in favor of the Bill of Rights, which says, and I quote, "... the right of the people to keep and bear arms shall not be abridged."
Depends on the law where YOU are. In MOST of the US, there is no requirement or procedure to register a gun- popular belief notwithstanding.
There is no best gun in Socom. Each gun has its own best advantage depending on your situation.
