If you mean between the players on a team, then the signals have to be learned by all of your teammates. Once everyone learns what they mean then they will know to look for them and what they mean. As for "How do you execute them?" Very quickly. It's a fast sport. What really works better than hand signals because you are busy watching the ball and the other players is voice signals. Agree on words that can be called out. "High", "Low", "Spike". Whatever words you want.
A pass is typically used to get the ball to the setter. you hold out your arms and connect your hands to form a triangle shape. you do not swing your arms, but rather, let the ball come to you.
Volleyball does not have a quarterback position.
Hurting your hands in volleyball is almost a given. I have been playing volleyball for over six years and I have jammed at least three fingers each season. Additionally, I have torn ligaments in my thumb and I need to get surgery. Volleyball is all about your hands. Your hands are involved in every play. If you are a setter, you need strong hands and fingers because your fingers are used in every play.

the setter
Yes, a back row setter can execute a jump set during a volleyball match.
The weakside hitter is in right front (RF). They are normally opposite the setter.
A "1". When the pass is perfect, your setter can barely set it, making it about half a foot above her head, right into the hands of your middle hitter.
