Of course you can't fall straight up and you can't fall sideways.

You can if you have initial motion in that direction.
The fall (obviously) is an acceleration: you do not fall at a constant
speed.
If you fire a shot upwards, the projectile has an initial acceleration
upwards (in the barrel of the gun) but this initial movement no longer
has any influence when the projectile exits the barrel and is in free
fall.
In this last phase, the projectile "falls" (i.e. accelerates) always
downwards and never in another direction.
