If Earth's mass increased, then the gravitational force between Earth and the moon would also increase. The moon would be more strongly attracted to Earth. The acceleration between the 2 would increase also.
The moon stays in orbit around Earth due to the gravitational force between them, which keeps the moon in balance between moving away and falling towards Earth. This balance maintains the moon's orbit around Earth.
The Earth is larger than the moon, and therefore only a fraction (1/50) of the Earth would theoretically "fit" inside the space of the moon. Therefore, 50 moons could fit inside the Earth.
The umbra of a moon is the completely shaded, or hidden from light, part of the moon. The penumbra of a moon is the part that is only partially hidden, or shaded from light. The antumbra is completely in the light, and no shadows are cast upon it.

If earth's moon was destroyed, then we will no longer have normal tide cycles.
High tides would be smaller and low tides would be bigger, but would still occur. The cause of the tides is the gravitational attraction between the earth and moon, and to a lesser extent, between the earth and sun. If the moon were further from the earth, its gravitational attraction would be less strong, and its effect on the earth's liquid envelope would be correspondingly less.
That would be at the moment of the New Moon closest to perihelion, which happens to be the one closest to New Years day or January 2. The moon is then in between the Earth and sun, while the Earth/Moon system is closest to the sun.
There is no atmosphere on the Earth's moon.
A lunar eclipse is where the Earth comes between the moon and sun, so that light to the moon is blocked out by Earths shadow. A solar eclipse is where the moon comes between the sun and Earth, blocking out sunlight to the Earth.
The volume of the Moon is 2% compared to the Earth. You would need 81 objects with the mass of the Moon to match the mass of the Earth.
