There are semiautomatic versions of the Tommy gun (Thompson sub-machine gun). They are legal to own. A fully automatic Tommy gun is legal in Texas only if you have the federal license.
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.

Depends on where you live, and how the Gatling Gun is operated. In MOST of the US, a hand cranked Gatling Gun is legal to own, if you can meet the legal requirements to own an ordinary gun. However, the last one I saw for sale was around $15,000.If the Gatling Gun is operated from a power source (think Jesse Ventura and the movie Predator), then it is regulated as a machinegun. That requires special registration and payment of fees.
Only if it was registered with the BATFE by May 1986. It is a machine gun.
If the possession charge was a felony, no, it is not legal to own or possess a gun.
in the US, yes. You may make a gun for your own use. You must be old enough to possess a gun, and it must meet legal characteristics of a legal firearm.
