Force of Gravity is the force with which the earth attracts bodies towards its center. It makes it possible for the bodies (mass) to stay firm on the surface of the earth. When we throw something upwards, it comes down as a result of the force of gravity.
The terms "gravitational force" and "force of gravity" are interchangeable and both refer to the same force exerted on objects due to gravity. When an apple is falling, the force of gravity (gravitational force) is indeed acting on it, causing it to accelerate towards the Earth.
By Gravity we mean the energy of Gravity E= - mGM/r = -mu/r. Force is the first derivative of energy so the force of Gravity is dE/dr = mu/r^2. Force is the first derivative for all kinds of energy.
This means that the force of gravity acting on an object is directly proportional to its mass. Objects with greater mass experience a stronger force of gravity pulling them towards the Earth.
If you mean the gravitatioal field - other options are possible - units of acceleration are used for that. The force of gravity, of course, is expressed in units of force.
No, mass and gravity are not the same. Mass refers to the amount of matter in an object, while gravity is a force that pulls objects with mass towards each other. Gravity is influenced by the mass of objects.
Gravity requires no direct contact, if that's what you mean.

8 times the force of gravity.

Not sure what you mean by "change gravity"; a nebula has mass, therefore it exerts a gravitational force.
Bigger masses mean a bigger force of gravity. Bigger distances mean smaller forces. Mathematically, the force is directly proportional to the product of the masses, and inversely proportional to the square of the distance.
"Gravity" is a force between any two objects. This specific force depends on the masses (more mass --> more force), and on the distance between the objects (more distance --> less force).
I believe is gravity. I mean is not only of the earth, every body of mass has gravity. But I believe that it is gravity if it was a general question. !

First of all, gravity is not a force, it is an acceleration. What you mean is the force of weight, which is the acceleration of gravity multiplied by mass (all forces are vectors, and gravity is not a vector.) When air resistance is subtracted from weight, you have the net force on a falling object (assuming those are the only forces acting on it.)
