no the object is in equiliberum (sp) where the net force equals zero. this is also true if the object is moving at a constant rate

An object can remain at rest even if a large number of forces are acting on it - but all the different forces must be mutually self-canceling.
Otherwise the object will not remain at rest.

The NET force on the object is zero -- in your point of reference. E.g. an object sitting on the ground, not moving, has a gravitational force pointing down on it, but there is a normal force -- equal and opposite in direction -- point up on it. The net is zero. However, your point of reference is the same as the object. That is, you're on the earth, too. If you were somewhere out in space looking at the object, then you would notice that the gravitational force of the sun would be acting on it -- and thus it would be moving.

For an object to be at rest the NET FORCE must be zero. However, that doesn't mean that no forces are acting on it, it just means that all the forces cancel out between themselves.

No. The could be two equal but opposing forces acting on it, Or even equal forces acting on all sides of the object.

If an object is at rest and remains at rest, then the vectorial sum of all forces acting on it is zero, in the frame of reference of the object.
There could be large forces: A 10,000 tonne ship is at rest. Gravity pulls the ship down with a force of 10,000 tonnes; it is countered by the 10,000 tonne buoyancy force of water keeping the ship afloat. The 50 tonnes push by the current and wind is countered by the 50 tonne pull by the anchor chain. And so on.

Incorrect. There may simply be a net force a 0. For example there may be equal forces coming from opposite directions, causing a net force of 0.

No, because gravity is always at work, but it is possible for an object to be at rest even when that force is pulling against it.

Any object at rest in a gestational field has the force of gravity working on it.

The object being at rest presumably on earth at an elevation or at sea level is subject to the gravitational pull of the earth, the 14.7 pounds of atmospheric pressure at sea level, any wind currents thats moving around it but not displacing it. This condition can be referred to as static inertia, inertia being defined as the ability of mass or a body to remain at rest or if moving to continue moving.
