Everything has gravity, the bigger it is the more it has. Moons DO have gravity, but it might be less than Earth's.

There is gravity. There is gravity on all planets, moons, and stars.
Our moons gravity.
Gravity keeps them in orbit around Jupiter.
Yes, approximately.
because their gravity is so strong that the moons are pulled in.
Moons orbit Jupiter because of the combined influence of gravity. and the forward motion of the moons. If there were gravity along, the moons would fall into Jupiter. If there were only forward motion, the moos would fly off into space.
In our solar system, at least, the planet with the greatest mass does happen to be the one with the most known moons. But I think the cause and effect work the other way. It's not the moons that give the planet strong gravity. It's the strong gravity of the planet that captures a bunch of moons.
