The centre of gravity does not, by itself, determine whether an object is at rest or in motion. The location of the centre of gravity, relative to where the object is supported, can contribute one of many forces that can act on the object. And it is is the [vector] sum of these forces which determines whether the object remains at rest or in uniform motion.
Only objects that have the exact size, shape, mass and density distribution can have the same center of mass. Any variation and the center of gravity would move. Furthermore, only objects that are geometrically symmetrical (think sphere) can have a center of gravity at their geometric center.
No, objects cannot have more than one center of gravity. The center of gravity of an object can however change.
that is gravity
Gravity pulls objects together and towards the center of the earth. The force of gravity depends on the mass of the objects and the distance between them. Gravity will speed up objects falling towards the earth and slow down rising objects.

All objects which have mass have a centre of gravity.
No, objects cannot have more than one center of gravity. The center of gravity of an object can however change.
Gravity pulls objects towards the center of the Earth.

Gravity
Toward the center of mass of the object or objects attracting you. Gravity also pulls it/them toward the center of mass of you.

Acceleration of rotating objects
gravity
The object's mass, and how far you are from its center of mass.
