No. Assuming the barrel is level (defined as perpendicular to the pull of gravity) then the bullet will leave the barrel horizontally and immediately begin to fall, like any other object subject to gravity.
There are aerodynamic forces from air resistance, but these do not impart lift to the bullet.
Often the gun recoils (per Newton's laws) in such a way as to raise the barrel after the bullet has fired.
At the instant the gun fires, the bullet is at rest- speed zero. As the expanding gasses from the burning gunpowder reach the bullet, they begin pushing the bullet up the barrel. It's speed is increasing- and the longer the push, the higher the speed. There IS a point of diminishing returns- where a barrel LONGER than the perfect length begins to slow the bullet- you have used all the expanding gasses, and now friction is slowing the bullet. If you had a barrel 20 ft long, the bullet would not make it all the way up the barrel, it would stop.For barrels on any realistically-usable weapon, a longer barrel will provide more momentum to the bullet than a shorter one. In addition, longer rifled barrels will also impart more spin, which will increase accuracy.
The breech is the rear of the barrel, where a cartridge would be loaded. The muzzle is the front end of the barrel. When fired, a bullet is driven up the barrel, and out of the muzzle.
IF the barrel is parallel to the ground, ALL bullets begin to drop as soon as they leave the barrel. To shoot at anything any distance away, the barrel is tiled up to some degree. Being pointed up, bullet WILL go up- and back down again. Try it with a stream of water from a garden hose, and you can see how it works. To spray water further away, you tilt the hose nozzle up- water goes up, and back down again. But point the nozzle straight out, water does not go up.
That would depend on the mass of the bullet, the bullet's velocity when it left the barrel of the gun, and from how high up the bullet was fired from.
If a gun was parallel with the earth and was fired and at that very instant someone standing by the barrel dropped a bullet from beside the barrel, both bullets would hit the ground at the same time. Bullets start falling the instant they leave the end of the gun barrel. That is why hunters hold their rifles at an upward angle. It looks like the bullet will shoot up into the sky. The bullet will follow a curved path toward its target.
Typically it is a set of holes in the upper side of the barrel near the muzzle. Part of the gasses pushing the bullet are released through those holes as the bullet passes them. Gasses going UP push the barrel DOWN, counteracting the recoil that flips the muzzle up.
You break a barrel and then you build a broom and you go and clean it up

When a bullet is fired from a rifle, a chemical reaction in the gunpowder ignites, rapidly expanding gases build up pressure, and the bullet is propelled out of the barrel at high speed. The rifling in the barrel causes the bullet to spin, improving accuracy and stability. Gravity will eventually cause the bullet to drop due to gravity and air resistance.

It can. The rifling in the barrel causes the bullet to spin. This usually keeps the bullet moving relatively straight (because of gyroscopic stabilisation). However, as the bullet slows down at longer ranges, the spinning can cause it to wobble and drift. This is called spin drift. Spin drift can be upwards, so yes, rifling can cause a bullet to go up, but only at extreme ranges.
