If you mean the same distance from the sun, it is because the moon orbits Earth nearly 400 times closer than Earth orbits the sun. This is less than the variation in Earth's distance from the sun due to its orbital eccentricity.
Phobos orbits Mars. So the distance between Earth and Phobos is essentially the same as the distance between Earth and Mars. This distance varies from 3-1 AU (astronomical units) to 3+1 AU. One AU is about 93 million miles.
Yes. All astronomical observations to date suggest that the gravitational constant is literally a universal constant ... the same everywhere in the universe.
Same units as are used to describe the surface gravity of the Earth, the moon, or any other body: Units of acceleration, such as meter/sec2 or feet/sec2 .
Answer: you would have to be specific there are a lot of moons orbitting Jupiter Answer: The distance from Earth to Jupiter's moons is the same as the distance from Earth to Jupiter. The distance from Jupiter to its moons is insignificant, and can be ignored.
The moon's average density is about the same as the density of mantle of the Earth.
Same as Jupiter, since Callisto is a moon of Jupiter.

Exactly the same. Mass is the same everywhere. The weight will be 1/6 less on the moon though.

Yes, the idea is that the units don't depend on local conditions such as the gravitational field.
It's not exactly obvious what this question means, but I would say there is no such planet in our solar system. The Moon has an average distance of 381,000 km and goes round in 29 days so its velocity is 0.96 km/sec. For a planet to have the same orbital velocity its distance would have to be 371 astronomical units, in other words about 120 times as far as Neptune.
no the earth is bigger than the moon

The same as between the Moon and the Earth. The distance from the clouds to the surface of the Earth is insignificant, compared to the Moon-Earth distance.The same as between the Moon and the Earth.

the
No, they do not have the same mass. The moon has much less mass than Earth.
