Yes. Mechanical energy is the sum of potential energy and kinetic energy; this includes gravitational potential energy.
Yes, an object's mechanical energy can be equal to its gravitational potential energy. Mechanical energy is the sum of an object's kinetic and potential energy, and gravitational potential energy is a type of potential energy determined by an object's position in a gravitational field. When the object is at rest or its kinetic energy is zero, its mechanical energy will equal its gravitational potential energy.

A. gravitational potential energy. When the coconut is still in the tree, it has stored potential energy due to its position in the Earth's gravitational field. This potential energy is converted to kinetic energy as the coconut falls, which is a form of mechanical energy.
If you leave earths gravitational field (sufficiently), objects will have a very negligible gravitational potential energy. You can consider it zero. But what if it were a compressed spring that you brought out into 'deep space'? It would still retain elastic potential energy. A bomb in deep space would still have explosive(?) potential energy. With that said, if you had two or more objects in deep space, they would have gravitational potential energy between the group of them, but not the earth.
The gravitational potential energy of two objects is negative because it is defined as the work done by gravity when the objects move closer together, which results in a decrease in potential energy.
It doesn't quite make sense for that to happen. Obviously it doesn't make sense from the point of view of energy conservation. Also, mechanical energy consists of kinetic energy - so all objects would suddenly have to stop moving. Mechanical energy also consists of potential energy (including gravitational potential energy), so all objects would suddenly have to be at the lowest possible gravitational potential - presumably, all objects in the Universe would have to come together into a black hole or something like that.
Gravitational potential energy
Gravitational potential energy can be transferred between objects when one object loses gravitational potential energy while another gains it. This transfer of energy typically occurs as objects move in a gravitational field, such as when an object falls from a height to the ground. The total amount of gravitational potential energy in the system remains constant, but it can be transferred between objects within the system.
The value of the Gravitational Potential Energy decreases as the distance (r) between the objects increases. This is because the gravitational force weakens with distance, resulting in a decrease in potential energy as the objects move farther apart.
when you stay on the ground the mechanical objects stay there too due to gravity.
A more massive objects have a greater gravitational potential energy.
