Yes. There are countless globular clusters in the universe.
Rigel and Deneb are not part of aging globular clusters. Globular clusters are tightly bound groups of old stars that orbit around galaxies, while Rigel and Deneb are individual bright stars that are not associated with globular clusters.
There are over 15 trillion globular clusters (150 per galaxy) in the universe.
A globular cluster (without "galaxy") is a large group of stars, in form of a sphere, within a galaxy. A galaxy may have thousands of such clusters. I am not sure whether the term "globular cluster galaxy" has any meaning in astronomy. It might be a galaxy with a lot of such clusters.
Globular clusters are dense groups of stars with close interactions that make it difficult for planets to form and remain stable. The strong gravitational forces and frequent stellar encounters can disrupt planetary systems, leading to their absence in globular clusters. Additionally, the metal-poor nature of globular cluster stars may hinder planet formation, as metals are important building blocks for planets.

The hottest stars. Generally, globular clusters contain mainly old stars, population II stars
two types of star clusters are Open clusters and globular clusters
Globular clusters are small groups of stars, while the milky way is a large galaxy containing hundreds of billions of stars, along with some of these clusters.
Actually the terms "Globular" and "Open" are not related to the number but the age of the stars. Globlular clusters are many old stars packed in spherical form (they look like hazy mothballs to the naked eye) and "open clusters" are many young stars formed close to each other. The constellation Pleiades is an example of open cluster.
Any major galaxy has LOTS of star clusters, including globular clusters, if that's what you mean.
Precisely because they are rounded, like a globe or sphere.
