They are called "Star Clusters".
A collective noun for a group of stars is a cluster of stars (small group) and a galaxy of stars (large group).
A small group of stars that appear to be close together are often known a cluster. Technically its an asterism.
A constellation is a group of stars that appear to be together in a group, but are not actually close to each other. They appear to be together because they are along the same general line from Earth to those stars. Also the constellations can change over time due to the position of the Earth. One star can have a surface temperature, but a group of stars does not have a common surface, or even an average temperature for the group.
A name given to a large group of stars and other bodies in space is a galaxy. Galaxies contain stars, planets, gas, dust, and other celestial objects bound together by gravity. The Milky Way is an example of a galaxy that contains our solar system.
