Yes it is. Everything you can see without a telescope (nd most of what you can see with a small telescope) is within the Milky Way galaxy with the notable exception of the Andromeda galaxy which you can see with the unaided eye. (But it should be pretty dark to be able to see it).
No, the Milky Way is a galaxy
No. It is a single galaxy.

A Star Cluster is a cluster of stars found within a galaxy or the intergalactic medium, and they don't usually have supermassive black hole centers or spiral arms. Star clusters contain around a thousand stars, compared to the Milky Way's 300 billion stars. In short, a galaxy is not classified as a star cluster.
Uranus is within the Milky Way Galaxy.
The Earth is part of the Milky Way Galaxy which in turn is part of the Local Group Cluster. The Local Group Cluster itself is part of the Virgo super cluster.
The Milky Way Galaxy is a spiral galaxy and open clusters are only found in spiral or irregular galaxies.
Orion is not a galaxy. It is an open star cluster in the Milky Way. It is also a nebula.
The galactic cluster in which the Milky Way is located is called The Local Group. (Not very inspiring, is it?)
Viewed from the Galactic North Pole, the Milky Way galaxy is moving anticlockwise.
