The Moon does not just go around the Earth. In reality, the two objects orbit about a common gravitational midpoint, called a barycenter. The mass of each object and the distance between them dictates that this barycenter is inside Earth, about three-fourths of the way out from the center.
Another moon would not affect Earth's gravity. The gravity a body exerts is determined by its mass, not by the mass of objects affected by it. This would, however affect other things, chief among them tides, which are controlled by the gravity of the moon.
All matter causes gravity. Every planet will have a gravitational attraction. Certainly Earth, Mars, our Moon, and the Jovian moons Callisto and Ganymede will be walkable.
All objects irrespective of size that have a mass have gravity.The moon has very little gravity in comparison to the Earth The moons gravity is around 17% of that on Earth whereas the Suns is 2,800 times that of Earth's The effect of the Moons gravity is easiest to recognise with tides on Earth.
Yes, the two moons of Mars, Phobos and Deimos, are held by Mars' gravity. The gravitational force of Mars keeps these moons in orbit around the planet as they move through space.
The moon's gravity is about 1/6th of Earth's.
The moons gravity holds them down!! The moons gravity maybe lower than the Earth's gravity but on the moon it is strong enough to win the tug of war with Earth's gravitational pull.
The moons gravitational pull is what causes tides.
The moon's gravity is essentially identical to 100% of the moon's gravity, and results in gravitational forces on its surface that average about 16% of the corresponding forces on the Earth's surface.
The moons gravity is less than that of the earth, since the earths mass is greater than the moons mass. Gravity is related to mass and distance from that mass. The greater the mass, the greater the gravitational field it has.

The moons gravitational pull on the Earth
Everything has gravity, the bigger it is the more it has. Moons DO have gravity, but it might be less than Earth's.
Yes, both Ganymede and Callisto, which are moons of Jupiter, have gravity due to their mass. However, the gravitational force on these moons is weaker than on Earth because they are much smaller and less massive.

The oceans
The moons gravitational pull on the earth lifts the Earth's oceans causing the ebb and flow of the tides.
