10 million give or take

That's a hard question to answer. It's probably between 20 - 50% of the adult population of America, depending on what study you are referencing.
Many experts claim that it's at least 1-in-4 Americans. Which would be 76,751,637 people according to US Census Bureau Data for 2009.
Multiple millions - as many as they want to own...
I doubt it.
300000
We do not know an exact number- lack of records, but it is estimated that about 1/3rd of all households have at least 1 gun.
373629
Tens of milliions.
There are no records. Texas does not require permits to own a 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.
No you do not have to be a gun expert to own a gun. As long as you are of legal age to own a firearm and you do not have any felony offenses on your record, you can 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

@ 1/2 of the population does not own a firearm.
