Galactic associations are groups of young stars that formed together from the same molecular cloud. Galactic clusters are larger collections of stars, often numbering in the thousands, that share a common origin and are bound together by gravity. Both associations and clusters provide important insights into the formation and evolution of stars and galaxies.
For sure - galactic clusters. Expansion of the universe is demonstrated via the redshift of galactic clusters (outside of the local galactic cluster which hosts the Milky Way galaxy). Pulsars may also provide some insight into expansion via the emission of their light signatures, but it is not generally considered a specific support (in and of itself).
Globular star clusters are members of the Milky Way galaxy. They are dense, spherical collections of stars that orbit the galactic center. These clusters contain thousands to millions of ancient stars and are typically found in the galactic halo.
Yes, the distribution and movement of galaxies in galactic clusters provide evidence for the big bang theory. The observation of cosmic microwave background radiation, galaxy redshift, and the uniform expansion of the universe within these clusters all support the theory of the universe originating from a hot, dense state and expanding over time.

the 3 clusters of PECs are Achievement Clusters , Planning Clusters and Power Clusters
They form galaxies, galactic clusters, and galactic superclusters.

Galactic clusters can vary widely in size, ranging from a few million light-years to tens of millions of light-years in diameter. The exact radius of a specific galactic cluster would depend on its size and composition.

what is the thin gas and clusters of stars surrounds the disk of the Milky Way Galaxy.
"The halo primarily contains individual old stars and clusters of old stars ("globular clusters"). It may be over 130,000 light years across. The halo also contains "dark matter," which is material that we cannot see but whose gravitational force can be measured." to shorten the answer - individual stars, clusters, and dark matter.
The Galactic halo is the spherical region surrounding the disk of a spiral galaxy which contains globular clusters and reddish population II stars.
