Minnesota requires you to have a permit to carry a handgun. Permits are not issued to persons under the age of 21. See link blow to Minnesota gun law.
You can keep your gun with you in Minnesota if you have a permit to carry.
No you do not. Only Gun permits, driving permits, and boating permits.
There are not. The state of Illinois does not issue gun carry permits of any kind, and until recently, you basically couldn't have a gun in Chicago at all.

Yes
No. California does not honor any "gun permits" from Nevada. I assume you are referring to the Nevada CCW (Concealed Carry of a Weapon) permit as Nevada does not have any actual "gun permits".
There are no records. Texas does not require permits to own a gun.
There are no permits required for paintball guns.
There is no such thing as a gun license in the US. There are concealed carry permits/licenses and dealers licenses.
If you mean a handgun carry permit, you can't. Illinois does not issue gun permits.
