Equal.
Yes, gravity is constantly acting on all objects even when they are at rest.
Net force is the addition of all forces applied. An example would be a still ball (a ball not in motion). The ball would be in "equilibrium" meaning that the ball is at rest, therefore, the net force of this ball would be 0.
You never know. The only thing you know about the forces on an object that's not accelerating is: They all add up to zero, and their effect on the object is the same as if no forces at all were acting on it. That's the same as saying that all the forces on the object are 'balanced'.
in equilibrium with a net force of zero
All the forces acting on each other are in equilibrium. For instance the restoring force upward from the ground/floor is equal to the strength of the force of gravity, which acts downwards.
All forces acting on it cancel out.

All objects on earth have the force of Gravity acting on them.

If a body is at rest ... or traveling at a constant speed in a straight line ... there could well be millions of forces acting on it. The only conclusion you can draw from the fact that it has no acceleration is that all the forces acting on it must add up to zero.
The force is said to be "equilibrant" when acting with other forces it would keep the body at rest ie in equilibrium. Hence equilibrant would be equal in magnitude but opposite in direction to the resultant of all the forces acting on the body.
Yes, there are always forces acting upon things, even when at rest (although all motion is relative so nothing is really "at rest"). There are some that are visible to the naked eye. For example, wind and corrosion. There are also forces that are not visible to the naked eye. Like the forces that make the electrons spin around the nucleus, the forces that hold the object together, etc....
For an object to be at rest, the sum of all the forces acting on that object must be zero.If you want to formulate a question, you can base it on that.
To move an object that is at rest, you must overcome all other forces that are acting on the object, such as friction.
