It depends on what you mean by "sell". If you mean put it on Ebay for trade, or on PBnation then no. you have every right to do so. If however, you mean to open a shop and sell goods then yes.
No.

You don't need a license to carry a paintball gun in the United States. To purchase a marker you must be 18 , to play at a field, insurance requires that you be ten, but can sign a wavier for yourself at 18.
No there is no licence required to purchase/operate a paintball marker. In order to play you must be at least ten (at most places) and 18 to purchase a marker, balls, or CO2.
A paintball gun needs CO2 (or HPA) to fire at all.
Yes. A paintball gun is not considered a firearm therefore a felon can purchase a paintball gun in Texas.
you need Co2 to fire any paintball gun, it is what physically moves the ball out of the barrel.
Yes you would need a firearms licence in N. Ireland however, You cannot because a paintball marker is classified as a firearm(if a mechanism has to potential of firing a projectile over 1 joule of energy out of the muzzle it is classed as a firearm) and the firearms reg act of 2005 basically states that no person can have a firearm's licence for a paintball gun because it can only be used for recreation purposes. cannot have justifiable cause to own one Licences have only be given out to people who own a paintball centre trust me i have been trying to get a licence for over a year now the PSNI will not allow it If you do have a paintball marker but no licence you could get a fine.
You would need zoning permits and insurance to open a paintball field.
