If you shoot a bullet downwards, does the gravity increases the velocity until the terminal velocity or the drag caused by the air decreases its speed?

Air resistance will decrease it's speed.  The muzzle velocity of almost all projectiles is much higher than their terminal velocity.

For example, a .30 caliber bullet has a terminal velocity of ~300 ft/s, but a typical .30-06 round has a muzzle velocity of 2500-3000 ft/s.
