The gravitational force between people hugging is extremely small and almost negligible. The force is determined by the mass of the individuals and their distance apart, but due to the relatively low masses of humans and the short distances involved in a hug, the gravitational force is far too weak to be perceptible.
You do not feel a gravitational tug from a person passing you on the street because the gravitational force between two people is extremely small compared to the force of gravity between us and the Earth. The force of gravity between two people is too weak to be noticeable in everyday situations.
"attraction"
Technically, a gravitational force exists between ANY two bodies with mass. This would include a force between your body and any given star in the sky. The force may be small, but technically it's there.
Gravity exists regardless of weight, as it is a force of attraction between objects with mass. Weight, on the other hand, is the force with which an object is pulled by gravity, and it depends on the mass of the object and the strength of the gravitational field it is in. So, gravity would still exist even if weight did not.
No, not everything that is not part of a system is gravitational potential energy. Gravitational potential energy refers specifically to the energy stored within an object due to its position in a gravitational field. Other forms of energy, such as kinetic energy, thermal energy, and chemical energy, can exist outside of a system as well.
Yes.
Yes it does.

The gravitational force between the Earth and the Moon will continue to exist and affect their orbits. Over time, tidal forces will cause the Moon to move further away from the Earth, which will result in a weaker gravitational force between them.
no
The only requirement for mutual gravitational forces to exist between two objects is that the objects have mass. That's usually a simple requirement to satisfy.

They believed an agreement must exist between the people and their leaders
By their gravitational effects.
Yes, that's basically what causes tides. ===================== And the moon. Lets not forget its role.
