The short answer is "yes". Many states, like NH, have very few restrictions on buying or owning firearms by anyone without a criminal record who has reached the age of 21. The federal government has made some rules that can make it illegal for someone with a restraining order against them to have firearms. Some states, such as MA, require residents to purchase permits to buy or carry firearms. The federal government has books of laws infringing on our right to keep and bear arms. These laws are getting worse almost daily. New legislation, often referred to the Veterans Disarmament Act, would make it illegal for any veteran who was diagnosed with Post-Traumatic Stress Disorder to own a firearm, even if it does not result in violent behavior. Depending on which version is (was?) passed, it could make it illegal for anyone who was diagnosed with Attention Deficit Disorder to own a firearm, even if they are not violent and don't have a criminal record. If someone filed a restraining order against you, you are no longer allowed to own a firearm until the restraining order is lifted. There are many other restrictions and exceptions, but for the most part, if you are a normal law abiding American, you can buy and own a firearm.

No. It is illegal for a felon to own or possess a firearm, and being a felon is a reason for denying a firearm permit (assuming you mean a carry permit) in every state that issues permits. A felon can sometimes have his rights restored, but for information on that, you really should contact an attorney familiar with the process.
No.

Local ordinances and state law determines whether or not you need a "permit" to own a shotgun. The laws and ordinances differ by locality.

No, it is illegal to own or use a paintball silencer without an actuall firearm silencer permit. You can buy mock suppressors, which look like silencers but do no significant effect for sound dampening.
If you mean a handgun carry permit, it depends on where you are. In the state of Tennessee, permits come up for renewal every 4 years. If you mean a permit to own a firearm, most states in the U.S. don't require one.
