If mechanical energy is conserved (like, if you did this on the Moon, where there is practically no air), when the bullet gets back to the ground it must have the same speed with which it started out. In practice, it will be less, due to air resistance.

Depends. The caliber of the cartridge, the weapon that fires it, and the angle (straight up, or tilted to one side?) all all variables that will affect how far (or how high) a bullet will go. No one answer for your question- sorry- EDITED AND ADDED: But here's a ballpark figure. If you take a large-caliber military or big game hunting rifle and shoot it into the air on a calm day with the barrel pointed about 35 degrees above horizontal, the bullet will reach about one mile (roughly 5000 feet) in altitude above the ground at the peak of its arc, and it will land on the ground (or water) about 3 miles away. It will land with a lot less speed then when it began its trip, but it will still be dangerous. If you fire the bullet straight up into the sky, it could go up to 10,000 feet altitude ---roughly 2 miles above ground level. That's why military aircraft consider any altitude below 10,000 feet to be "within range" from small arms fire from the ground. Above 10,000 feet they're safe from regular rifles and hand-carried machineguns, but bigger cannons can still reach them.
it all depends on the speed that the bullet is shot at. other contributing factors include the angle of the shot and the distance from the ground that the bullet is shot at. sadly, the x-factor of this question is that the ground determines how far it will ricochet. if the ground is water, it will not ricochet.
It starts to lose momentum the second it comes out of the barrel. It depends on where you shot it when the momentum is totally depleted (if you shoot straight up or parallel to the ground).
To many variables. Depends on caliber of bullet, type of dirt, type of ammo, distance from gun to ground,etc...

No. The horizontal distance depends on how close the the ground the gun is. From the firing position, a bullet dropped to the ground will strike the ground in the same time as a bullet shot horizontally forward.
Yes, a bullet can be shot with no gun. A bullet does not need a lot of speed to kill someone. Say someone threw a bullet to the ground, it might bounce back up and hit you, thus causing you to die or be injured

Exactly the same speed as when it left the barrel (ignoring the distance from the gun to the ground). Why should we do that?

Yes, if the bullet is shot with escape velocity.

A bullet fired parallel to the gound, over flat ground, and a bullet dropped at the same time from same height will hit the ground at a time so close to each other as to be the same.
The bullet has a great deal of kinetic energy, because of its high speed. It also has a little bit of potential energy relative to the ground, because of its height above the ground.
