In most states, you can purchase a gun in a gun store, and the entire process takes 20 or 30 minutes. A few states still have a waiting period of several days, I believe. In most states, person to person gun sales don't require you to go through a gun store, but some do.

About 6 to 7 days

It depends on what you mean, but generally speaking, a felon can't get a gun license.
NICS takes a couple of minutes.
best bet is to take it to a gun expert
1 sec or so
18 for a long gun, 21 for a handgun, money, compliance with all federal, state and local laws.
It depends on the mag size. How about timing yourself?
