Mass
That's the 'resultant' of all the forces, and the 'net force' on the object.
When an object is at rest, the forces acting upon it are balanced - there are no unbalanced forces.

Action-Reaction Forces.
The force exerted on a scale by an object and other forces acting.
That's the 'resultant' of all the forces, and the 'net force' on the object.
However many there are exerted on the object. Usually there is gravity, friction, and another force exerted on the object.

Buoyant forces
The "reaction" force.
An internal force is a force acted upon by an object to force another object's movement internally. An external force is a force exerted on an object based on the objects position and force applied on the object which causes the opposite forces change in motion.

Whether they are, or are not, exerted depends on the physical situation. For example, magnets won't lose their magnetic force if you make them touch. And if objects stick together, they are certainly exerting a force on one another.
