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.
Yes, gravity does depend on the planet you are on. The force of gravity is determined by the mass of the planet and your distance from its center. Therefore, gravity will be different on each planet based on these factors.
Gravity holds the atmosphere around the planet. Gravity is the force that attracts a body toward the center of the planet. For most purposes Newton's laws of gravity apply, with minor modifications to take the general theory of relativity into account.
Mercury has the smallest mass of the 8 planets at 5.5% of the mass of the Earth. It therefore has the least gravity of all the planets.
The gravity of a planet is directly proportional to its mass, and inversely proportional to the square of the distance from the center of mass. For the gravity on the surface of the planet, the distance is just the planet's radius. Thus, if a planet has three times the mass, it has three times the gravity. If you are three times as far away, the gravity decreases by a factor of nine.
Mercury, because it's the smallest if you don't consider Pluto to be a planet.

the bigger the planet the more gravity.the smaller the planet the least gravity
Yes. At least, the gravity resulting from planet Earth.
Jupiter has the strongest gravity. The bigger the planet, the stronger the gravity. The moon is kind of small, so it's gravity is weaker.
Jupiter, as it has the most gravity.

Mercury is the least massive of all the planets. The least massive planet is Mercury (0.055 Earths). However, the planet with the weakest gravity is Mars. I am of course not treating Pluto as a Planet (as it is no longer categorized as a planet), if I were to count Pluto then it would be the least massive ( 0.0021 Earths).
Earth is the most massive terrestrial planet, so it has the highest surface gravity.
In our solar system, Jupiter
A force that most affects the path of a planet around the Sun is gravity.
