Biju belongs to Taurus, and M45 is also called Pleiades cluster, and Pleiades VI is one of them. The Pleiades cluster belongs to Taurus, so the Pleiades cluster is certainly a part of Taurus. As for MenCallinan, it is a bright star in Auriga, adjacent to Taurus but not subordinate.
So of course, these four don't belong to the same constellation.
