Globular clusters and very small galaxies.
All stars originate in (collapsing) gas clouds - consisting mainly of hydrogen - and usually in large groups (hundreds to thousands of stars forming together).

Star clusters (or star clouds) are groups of stars.There are two types of star clustersGlobular clusters: are tight groups of hundreds of thousands of very old stars, which are gravitationally bound.Open clusters: are more loosely clustered group of stars, generally contain less than a few hundred members, and are often very young.See related link for more information
That must refer to an OPEN CLUSTER; according to the Wikipedia article on "Star clusters", such open clusters "usually contain up to a few hundred members [i.e., stars]".
The other stars do not appear as bright as the sun because they are much farther away. Even the closest stars apart from the sun are hundreds of thousands of times farther away. In terms of actual brightness, some stars are brighter than the sun.
Hundreds of thousands.
A clear night and normal eyesight.
No, a star cluster would be a group of stars; our solar system has only one star in it - the sun, with planets in orbit around it. A star cluster, by contrast, is a much larger structure - a group of from hundreds up to hundreds of thousands of stars (globular clusters can have millions of stars) bound together by gravity. It might be better to say there are star clusters inside our galaxy, the Milky Way.

There are probably hundreds, or thousands, of stars at approximately that distance.

Our solar system is pretty small. There are hundreds of thousands of other solar systems with stars in them. That is what you see.
They are so far away - the closest stars are tens of thousands, or hundreds of thousands, times farther than the planets - that any movement would take years to be noticeable.
The plural form of the noun star is stars, e.g. "On a clear night, you can see hundreds of thousands of stars."

The smallest galaxy - a dwarf galaxy - will contain stars upwards of 30 billion stars. You are thinking of an open cluster, which as the name suggests, is a cluster of stars, not a galaxy. An open cluster is a group of up to a few thousand stars.
Galaxies contain stars and nebulae, as well as a large variety of other phenomena.
