do these stars just start going off in different directions or is there a pattern ? would these stars be considered related?

Typical open clusters contain from a few dozen up to thousands of stars. Globular clusters can contain a million or more stars.

What distinguishes the two types of cluster is the degree of gravitational bonding - open clusters are loosely bound and the stars gradually disperse. This is why the sun is not closely associated with a large number of other stars - in the 5 billion years or so since its birth, the cluster it was born in has scattered.

All the globular clusters in our galaxy are very old, older than the sun. It is thought that they may have formed at the same time as the galaxy, though another theory has it that at least some of them are the cores of small galaxies absorbed by the Milky Way. Although the Milky Way can no longer form such massive clusters, relatively young clusters of hundreds of thousands of stars have been observed in nearby galaxies.

At some point in the early universe, whole galaxies coalesced out of the primordial gas clouds, but such "nebulae" no longer exist.

Anything from millions to billions and of course everything is ordered by gravity, mass, velocity. You know basisc laws of physics.
