Anyone can define a zero of potential energy, from which they are going to measure any other energy elsewhere. Like height, you take your zero to be the soles of your feet, or for a mountain, the sea level, or for a battery cell, one end of it. It may or not be possible to find a place in the universe where there is no lower gravitational potential. Note, usage is generally potential energy=potential x quantity (mass, charge etc).
No, it is not possible for a person to have zero mechanical energy. Mechanical energy is the sum of an object's kinetic and potential energy, and as long as the person is in motion or has the potential to be in motion, they will have mechanical energy.
The potential energy at ground level is typically zero, as the reference point for potential energy calculations is often set at ground level. This means that any object at ground level would have zero potential energy due to its height above the ground.
Any object that is at "level zero" has zero potential energy. In the case of gravitational potential energy, this level is sometimes defined to be ground level, sometimes (in Astronomy) at an infinite distance (in this case, any object that is closer than infinity has a negative potential energy).Any object that is at "level zero" has zero potential energy.

This can easily be understood with conservation of energy. Assuming that no energy is lost, potential energy is continuously converted to kinetic energy, and vice versa. At the mean position, the potential energy is zero, therefore the kinetic energy (and hence the velocity) is at maximum.This can easily be understood with conservation of energy.

Yes, in certain contexts, energy can have a negative value. This can occur in physics when calculating potential energy or in quantum mechanics when considering energy levels below the zero-point energy.

yes it is, but you can only have kinetic energy of the object is in motion and potential energy if the object is any height above zero
Zero

Sure, any object at the reference level or ground level (whatever you define to be the ground level, for your calculations) will have zero potential energy; if it moves, it will have a positive kinetic energy. What's more, if the object is belowthe selected reference level, it will have negativepotential energy. In this case, even if it doesn't move, its kinetic energy (zero) will be greater than its potential energy (which is negative).

Yes, in certain contexts, energy can have a negative value. This can occur in physics when calculating potential energy or in quantum mechanics when considering energy levels below the zero-point energy.
Yes, a system can have negative potential energy. This occurs when the system's configuration is such that the potential energy is lower than a reference point, often taken as zero potential energy at a certain distance or position. This can happen in systems where attractive forces dominate over repulsive forces, leading to a negative potential energy.
