Yes. The massive giant planets have far more moons than the less massive terrestrial planets.
No. The mass of a planet affects the number of moons it has. More massive planets tend to have more moons.
Jupiter and Saturn are the most massive planets in the solar system and so have the greatest gravitational effect.
The total mass of all the planets, moons and asteroids, etc. is approximately equal to 0.14% of the mass of the Sun. Of that, more than half is the mass of Jupiter.

Gravity, the mass of the planets, and how many and what life forms exist on each. Also the sun, and each planet's moons.

Planets have moons because matter is attracted by gravitational force to objects with a greater mass than them.That is why moons orbit planets and are never larger than their host planet.

because the smaller planets have less mass, which means less gravity, so they won't attract any moons.
"Weight" is not really a good word to use. A better term is "mass". The outer planets all have moons, and these can be used to get a value for the planet's mass ... the orbital period of a satellite depends on the mass of the primary and the semi-major axis of the orbit. It's possible to get quite good mass values for the outer planets by studying the orbits of their moons.
