Lots of wrong answers here!
"Galactic cluster" is a synonym for "open cluster" and does not refer clusters of galaxies! It refers to the fact that open clusters are found within the disk of a galaxy, as opposed to globular clusters which are external to the disk. Associations are looser groups of stars which share a common direction and speed of motion, which probably started out as an open cluster, but have since spread out.
The Sun is part of the "Local Association," also known as the "Pleiades Moving Group."

The sun is within a galaxy, and a galactic cluster is a cluster of galaxies, not stars. It's a bit silly to say that the sun is in a galactic cluster, but the group of galaxies around the Milky Way are referred to as a cluster called the Local Group.
A stellar association is a loose cluster of stars which have the same origins; the different types of stellar associations are based on what kinds of stars they consist of. The sun is not a part of one, though it is at the edge of the Ursa Major Moving Group. This is the closest stellar association to us, but the sun is ten times as old as the stars in this group, so it is not considered part of it.

the sun is part of a loose association of stars dubbed "the orion stream", according to various studies, this association was once an open star cluster that gradually drifted apart as the stars aged.....it is also part of a galactic cluster in the sense that the sun is a member of the Milky Way galaxy which is one of many galaxies in the cluster known as the local group.....

Our sun is part of a galaxy (..the Milky Way Galaxy..) which is one member in a galactic cluster known as the Local Group. As far as is known our sun is a single star and not associated with any other(s).

Nope, the sun isn't part of any cluster. The cluster the sun once formed from has long dispersed throughout the milky way.

stellar association.
if we were talking about the milky way as a reference point then we'd compare it to the local galactic cluster

The sun may be associated with a number of stars in the Big Dipper which have a common motion. They and we are heading in a similar direction towards Sagittarius, but they may or may not be linked.
