Jovian ________________________ Difficult to predict, based on mass alone.
No lower limit has been formally defined; the lowest-mass accepted planet is Mercury - 0.055 times Earth's mass. The largest planet in our Solar System is Jupiter, at 318 times Earth's mass. Larger planets are known to orbit other stars; the upper limit should be about 13 Jupiter masses or about 4000 Earth masses; an object with more mass than that would be a brown dwarf.
Yes. Earth is about 6.5 times larger than Mars and has more mass.
The more gravity a planet has, the more you will weigh on that planet. The amount of gravity that you feel depends on two things: the mass of the planet and the distance you are away from the center. Uranus has about 14 times the mass of earth, but also about 4 times the radius. Because you are some much farther away from the center of the planet, the force of gravity you feel is less. The effect of mass of a planet on the gravity of that planet is equal to the effect of the radius squared. In the case of Uranus, the radius squared is about 16 times that of Earth's radius squared, and the mass is about 14 times that of Earth. An approximation of your weight on Uranus based on these numbers would be: (Weight on Earth)*(14/16) (You can calculate the gravitational pull between two objects using the formula Fg = G(m1m2)/d2 where Fg is the force of gravity, m1 and m2 are the masses of the objects, d is the distance between objects, G is 6.67x10-11, and the units are newtons, kilograms, and meters.)

The moon and the planet it orbits that have the highest ratio of their masses are Earth's moon and Earth. The earth is only about 81 times as massive as its moon. In the #2 planet/moon mass ratio among the eight planets, Saturn is 4226 times as massive at Titan.
Your weight is directly proportional to the mass and gravity of the planet, if the planet has a greater gravity and mass, you will weigh more.
No, the gravity of this planet will not be greater than that of earth. If the new planet has a mass equal to that of earth, its total gravity will be the same. There is a little ambiguity regarding 4 times earth density and half the earth's diameter if the idea is to keep the mass of this proposed planet the same as the earth. But setting that aside and assuming that the mass of the new planet is the same as earth's, the gravimetric field will be the same. Gravity is proportional to mass, and identical mass yields identical gravity. Now to the good part! The surface gravity of the new planet will be considerably higher than the surface gravity of earth. Both planets have the same mass and the same gravity, but a person standing on the surface of the new planet will be experiencing a whole lot more force pulling on him. All the mass of the new planet is beneath this person, but he's a lot closer to the center of gravityand will weigh a whole lot more.
Yes, Saturn does weigh more than Earth. Earth's mass is 5.97224 kg while Saturn's mass is 568.324 kg. Saturn consists of 95.16 Earth masses.
The four gas giants: Jupiter, Saturn, Uranus, Neptune, all have more mass than the Earth.

The distance from the center of mass to Earth, times the mass of the Earth, must be equal to the distance of the center of mass to the Moon, times the mass of the Moon. (For more than 2 objects, the calculation is somewhat more complicated - reading about "center of mass" can give you an idea.)The distance from the center of mass to Earth, times the mass of the Earth, must be equal to the distance of the center of mass to the Moon, times the mass of the Moon.
