The gravitational acceleration at the surface of the Earth is 9.8 meter per second per second. To convert between weight (in Newtons) and mass (in kilogram) a factor of 9.8 (or roughly 10) is required.

The earth pull an 1 N apple with a force of 1 N towards the center of gravity of earth. The apple do not posses enough mass to pull the earth. (100g)
an object is like 3 to four pounds it dipends on what the object is > Its the force generated by gravity that attracts the earth and the object together. Normally its measured in kilograms (force) 1 kgf = 9.80665 newtons (force)

There is gravity on the moon. Basically there is the gravity from the moon itself, which is (on the surface) about 1/10 of the gravity on the surface of the earth. Then there is the gravity of the earth, which makes the moon rotate around the earth (in one lunar month ~= 4 weeks). Lastly there is the gravity from the sun, which makes the earth + moon revolve around the sun in 1 year. Everything with mass has gravity, but it is only measurable on a human scale if the mass is as large as the moon or the earth. Even the gravity pull from your fat neighbor kid is minuscule.
1. The earth has greater mass 2. the earth is closer to the sun
There is not zero gravity on the moon. Any object with mass has gravity (even a cotton ball). However, the more dense and more massive an object, the larger its gravitational pull. This is why, even though a tennis ball does have gravity, it has no effect in relation to the gravity of the Earth. The Moon has something like 1/6th of the Earth's, so if you weighed sixty pounds on Earth (eat something!) you would only weigh 10 on the Moon.
It is 1.235 ms-2 or approx 1/8 of the earth's gravity.

Gravity obeys an inverse-square law. The force is inversely proportional to the distance squared. That means at 1/10 the distance the force is 100 times stronger. The pull also depends on the mass of the Sun and the mass it is attracting. If you imagine a 1 kilogram "test " mass on Earth and an identical test mass on Saturn, then the pull on the mass on Earth will indeed be 100 times the pull on the test mass on Saturn.
