A cluster of Stars is more of a larger group of stars that are formed in the same area of a galaxy. Although in the same general area, we could be talking several light years. A Star system is on a smaller scale, where planets and stars are close enough to orbit about each other, the closeness means that the gravitational effects they have on each other are far stronger and more apparent. Our star, the sun, is the only star in our solar system, but other star systems are made up of 2, 3 or more stars that are fairly close to each other and orbit about each other.
open cluster
It can be called a star cluster, an open cluster or an asterism.
The type of star cluster where stars are grouped together in a loose formation with a wide variety of distances between each star is called an open cluster. Open clusters typically contain a few dozen to a few thousand stars and are often found in the arms of spiral galaxies. They are characterized by their relatively young age and lack of a dense core, allowing for the more scattered arrangement of stars. Examples of open clusters include the Pleiades and the Hyades.
globular cluster
The Solar System. Multiple solar systems make up Galaxies.
The oak leaf cluster indicates that the decoration has been awarded a second time. Thus a bronze star with oak leaf cluster means the person won two bronze stars. Michael Montagne
A galaxy contains planets and a star system contains only stars.
A star cluster is a cluster of stars, so clearly a star cluster must be larger.

stars are far and the sun is close
A star is an individual body like the sun, a constellation is a cluster of star systems.

A solar system is smaller. There are billions of solar systems in a single galaxy.Each star is a solar system. (some have planets, some don't)When you look at the sky at night, every star is a solar system and all of them are part of the Milky Way galaxy.A galaxy cluster is a group of galaxies.
Constellation or "asterism". The difference is that "constellations" are officially recognized by the International Astronomical Union, while an "asterism" is any other pattern or grouping of stars.
That can be a binary star, a triple star, etc. - in general, a "star system".
