Given that characters have no hands, I'm assuming that you mean a slight "knockback" effect once a projectile was shot.
I believe that kick animation could be used for that
If I'm mistaken, please explain what you mean by a "shooting" animation
For the laser - the hurt animation eyes could be used and used on different sprites, perhaps the crouch
For the shoot animation - the kick animation's(fourth from top) third sprite could be used for shooting in case you add some form of gun
the license Creative Commons Attribution v4.0 International should allow you to edit the sprites, so feel free to do so
As for me adding the animations - it was mentioned in the description that the sprites were originally made for a game that was abandoned, therefore I have no intention of adding any additional sprites/animations
