If a planet has multiple moons, why don't they ever hit eachother? Why don't they get pulled into the planet?

The reason you see stable orbits with moons and other natural satellites today is that these are the survivors. In the history of our solar it is likely that many did strike each other (forming larger objects or obliterating each other), many flew out away from the planet, and many probably were pulled into the planet's atmosphere.

Just out of chance, a few remained, safe in stable orbits.
