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....
When an object is at rest, the forces acting upon it are balanced - there are no unbalanced forces.
If the forces acting on an object are balanced, it means that the net force on the object is zero. In this case, the object will either remain at rest if it was initially at rest, or it will continue to move with a constant velocity if it was already in motion.
in equilibrium with a net force of zero
If the net forces acting on an object amount to zero, that object is at rest.
There can be forces acting on an object while it is at rest, as long as the forces cancel each out. For example: a block laying on a table feels the force of gravity pulling it down, but the table pushes up with the same force. Therefore, the forces cancel and the object remains at rest.

All forces acting on it cancel out.

Usually gravity and friction.
Yes. Forces with identical value but with opposite direction will produce no displacement.
An object at rest has zero acceleration. If the set of forces acting on a moving object is balanced, then the moving object also has zero acceleration.
Yes, if the forces are equal and acting in opposite directions, the net force will equal zero and that object can be said to be at rest.
