A collection of from two to several hundred galaxies which are much more densely distributed than the average density of galaxies in space.
Super clusters.

No. Nor are they completely random: they form large groups (star clusters) in some places, and, on a larger scale, galaxies.
Cluster's form because gravity gradually builds a center of mass which over time accumulates more and more matter which can explain the formation of galaxies as well as globular clusters.
A supercluster.
galaxies are in every direction in space there in clusters and super clusters
galaxies
yes
A collection of galactic groups form a cluster of galaxies. A supercluster is the largest known structure. Galaxies can exist outside of a group or cluster, but the estimated amount is only about 5%. However, there is a possibility that these galaxies may have interacted or merged with other galaxies in the past,

The galaxy clusters are the solar systems orbiting the galaxies.
They form galaxies, galactic clusters, and galactic superclusters.

Galaxies form groups called galaxy clusters, so they would orbit the center of mass of the galaxy clusters, just as our Solar System orbits the center of mass of our galaxy.Galaxies form groups called galaxy clusters, so they would orbit the center of mass of the galaxy clusters, just as our Solar System orbits the center of mass of our galaxy.Galaxies form groups called galaxy clusters, so they would orbit the center of mass of the galaxy clusters, just as our Solar System orbits the center of mass of our galaxy.Galaxies form groups called galaxy clusters, so they would orbit the center of mass of the galaxy clusters, just as our Solar System orbits the center of mass of our galaxy.
All galaxies are massive clusters of stars scattered across the universe. Many galaxies take the same form, for instance, spiral and elliptical galaxies. Some galaxies also have a black hole in their center.
Galaxy clusters typically have anywhere from 50 to 1,000 galaxies.
