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.
Jupiter
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.
The force of gravity of a planet is a product of its mass.
I'm quite sure that the planet with the highest gravity is indeed Earth, because even though it's not the largest, it is the densest. And gravity comes from density, not size. Also, the other planets are mainly comprised of gases, not liquids metals and rocks like the center of the earth.

the bigger the planet the more gravity.the smaller the planet the least gravity
Yes. At least, the gravity resulting from planet Earth.
The planet that has the largest acceleration of gravity is Jupiter. The planet with the least amount of gravity is Mercury. Actually, Pluto has less gravity than Mercury, but Pluto is not classified as a planet any more.
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.
Mercury, because it's the smallest if you don't consider Pluto to be a planet.
Jupiter has the most gravity out of all the planets
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).
Jupiter
Earth & Venus.
Earth is the most massive terrestrial planet, so it has the highest surface gravity.
