Gravitational potential is a form of energy, so it has the same units as any other form of energy. It also has the same dimensions as torque, although torque is not a form of energy per se.
Mass, density, shape, and color of a solid object are the same in space as on earth.
They all have the same gravitational potential energies.
It is a type of potential energy, but there are other types of potential energy, too.
When they're both at the same height, the heavier object has more gravitational potential energy.
They are all types of potential energy, that is, energy that is related to the position.
No. Gravitational force is the pull an object experience from gravity. Gravitational energy is the energy an object has from its position in a gravitational field. An object moving up in a gravitational field gains gravitational energy.

Gravitational energy is the potential energy associated with gravitational force. If an object falls from one point to another point inside a gravitational field, the force of gravity will do positive work on the object, and the gravitational potential energy will decrease by the same amount.
-- If the velocity is horizontal, then gravitational potential energy doesn't change. -- If velocity is vertical and upward, gravitational potential energy increases at a rate proportional to the speed. -- If velocity is vertical and downward, gravitational potential energy decreases at a rate proportional to speed.

I assume you mean the gravitational potential energy. This is proportional to the mass, so if you change the mass by a factor of "a", the gravitational potential energy will change by the same factor of "a".
No, force and energy are not the same dimension to start with. Gravitational force on an object is equal to mass*(gravitational acceleration) {dimensions Mass*Length/Time²}Kinetic energy is (1/2)*mass*(velocity)² {dimensions Mass*Length²/Time²}. If you look at these, Force, multiplied by length has the same dimension as Energy. And in fact you have other forms of energy:Work is Force times distance;Potential energy = mass*(gravitational accel)*height = (Force due to gravity)*(height), height is a distance or length.

The gravitational potential energy would be less for the same height above the surface. This is because the gravitational constant on the moon is less than that of the Earth. Potential energy is defined as mgh, where m is the mass, g is the gravitational constant, and h is the height.
