Groups at different scales (from smaller to larger) are called:* Multiple stars (two or more stars that are gravitationally bound)
* Star clusters
* Galaxies
* Galaxy clusters
* Superclusters
Galaxies, perhaps.
Gravity depends on mass. The Sun has a large mass, therefore, a large gravitational attraction.
The moon will probably never be destroyed by the Earth's gravitational attraction because it is in a stable orbit. Its orbit is kept stable by its high velocity, therefore the only way Earth's gravitational attraction could pull the moon out of its orbit and towards the Earth is if its course is changed or it is slowed down tremendously, perhaps by a large impact such as a meteor.
Because of gravitational effects from Jupiter.
Gravitational force is the attraction between two masses. It can be explained by Force=(Mass1*Mass2)/Distance. Everything is attracted to the earth because the earth has such a large mass. So on a small scale it is just about impossible to create gravitational force.
Immense gravitational forces would cause large mass objects to be stretched and compacted as it nears the black hole. Whatever is closer gets pulled in first, providing for unequal gravitational attraction.

This is technically not true. All forms of mass exert gravitational attraction on one another. However, since the Earth is billions of times more massive than most objects, the gravitational force of the Earth is commonly seen. The gravitational force between a stapler and a computer monitor is not large enough to make the two objects fly across a room to get to one another. However, both do exert a gravitational attraction on one another.

For breeding at rookeries, or at a food source.
When ANY two objects move closer together, the gravitational forces between them become greater.
The gravitational field depends on masses, and the distances to the masses. The gravitational field will be stronger close to large masses, such as the Sun and planets; but there is nowhere in space where you would be entirely free from a gravitational field. For example, if you go a thousand light-years away, the gravitational attraction of the entire Solar System would be insignificant, but you would still have the gravitational field of the Milky Way.
