Its possible, if you prepare ahead of time. In order to stand on one foot your center of gravity must line up with the leg you are standing on. When standing normally on two feet your center of gravity lines up with your crotch. If before lifting one leg you first bent your body sideways so the center moves over one leg, then you could lift the other leg and remain balanced.
No, a scale measures weight, which is the force of gravity pulling you toward the center of the Earth. Without gravity, there would be no weight to measure.
No, the center of gravity of a meterstick is not always located at the 50-cm mark. The center of gravity of an object is the point where its weight is considered to act. For a uniform meterstick, the center of gravity will indeed be at the 50-cm mark because of its uniform density distribution, but if the density distribution is not uniform, the center of gravity could be located at a different point.
The centre of the cross-section, halfway along the length of the rod.
That "point" in a body where the entire weight of the body can be represented to be present. Extend your knowledge by exploring where the center of gravity would be for metal shapes formed in the shapes of circular, square, rectanglar, hexagonal rings with metal rods. Where would the center of gravity be, on the ring or outside the ring?
The center of gravity of a body is the point at which the body's weight is considered to act. It is the point around which the body's mass is equally distributed in all directions, resulting in balanced forces. The center of gravity may or may not coincide with the geometric center of an object, depending on its shape and distribution of mass.
If its already moving.

No - without gravity, galaxies would not have formed, planets would not have formed, stars would not have formed.

Gravity is the only way to run a car without fuel Well the wind could push it.
Without gravity we could not stay on the surface of the Earth -- but that wouldn't matter, because gravity is what keeps the Earth from flying apart.

One simple example of a center of gravity could be a ruler balanced on your finger. Just at the point where your finger in located and the ruler does not fall is the center of gravity for your ruler. Now, put a quarter on one end and move your finger toward the quarter until it is balanced just like before. Same results, but the center has changed because one of the two points has changed it mass.
As you go down below the surface, the force of gravity would decrease, because now part of the Earth is attracting you from above, and less from below. At the center of the Earth, gravity would be zero.
