The effects would only combine for an object outside the Earth-Moon system (such as an asteroid). Otherwise, objects near the Earth and Moon will experience gravitational effects from both. The Earth's gravity holds the Moon in its orbit, and the Moon's gravity affects the Earth, notably causing the ocean tides.
Earths gravity keeps the moon from flying off in the same way the sun keeps earth in balance.
The moons gravity 'pulls' the earths water creating a 'tide.'
No, a planet's moons and atmosphere do not directly affect its gravity. Gravity is primarily determined by the mass of the planet itself; the more massive the planet, the stronger its gravitational pull. While moons can influence tidal forces and an atmosphere can affect pressure and weather, they do not change the fundamental gravitational force exerted by the planet.
Earths surface of gravity is 4.6m/s2 more than moons.
Of the planets in our solar system, Mars has the lowest surface gravity of around 38% of earths - over one third. This comes closest to the 25%. We then have moons and dwarf planets, but these have much lower surface gravities.
Earths gravity keeps the moon from flying off in the same way the sun keeps earth in balance.
The moon's gravity is about 1/6th of Earth's.
The earth has a colossal size more mass
There is no atmosphere on the moon. There is insufficient gravity to keep an atmosphere there.
The moons gravity 'pulls' the earths water creating a 'tide.'
Tidal movements result mainly from the pull of the moons gravity on the ocean.

the moons gravitational pull
About 0.183g, where one g is the earths gravity, so about one fifth of the earths gravity. It is similar to our own moons surface gravity.
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.

Your would weigh 1/6th as much as you do here on mother Earth. The how is our moons' mass, and therefore its' gravity, is about 1/6 as much as the Earths'. Its' gravity well is not as deep as the Earths.
