Yes.
A galaxy typically has several star clusters.
Stars, star clusters, distant galaxies, galaxy clusters, nebulae, ...
global clusters, open clusters and star clusters. (:
Planetary systems, star clusters, galaxy groups, galaxies, galaxy clusters, superclusters in order from smallest to largest.
Star clusters are typically located within the Milky Way galaxy. While there are some star clusters that are closer to Earth than other parts of the Milky Way, overall the Milky Way galaxy contains a vast number of star clusters that are more spread out.
Any major galaxy has LOTS of star clusters, including globular clusters, if that's what you mean.
Earth belongs to the Milky Way galaxy, which contains numerous star clusters. Specifically, our solar system is located in the Orion Arm of the Milky Way, but it is not part of a distinct star cluster. Instead, it is part of the larger structure of stars within the galaxy. The Milky Way itself is a barred spiral galaxy with various clusters, including globular clusters and open clusters.

They are located only in the ARMS of galaxies, not outside.
Nebulae or star clusters within the Milky Way Galaxy.
The question contains the answer 100,000. "if each of these star clusters contains 100,000 stars, how many stars exist in these clusters" If you mean the total number, are you seriously saying you don't know how to multiply 100,000 by 158?
A huge star group that rotates around a common center is called a star cluster. Star clusters can be classified into two main types: globular clusters, which are tightly packed groups of stars, and open clusters, which are looser groupings of stars.
