The 'other' mothers would have had children of their own. There was the other Mary, the mother of James the younger and Joses, and there was the mother of the sons of Zebedee, John and James. And there was Mary's sister, apparently also named Mary, the wife of Clopas. Jn. 19:25
Apparently Mary was a common name and John and James and Judas and Simon.
Does this rule out the possibility that Mary, the mother of our Lord Jesus, had children by Joseph? Isn't that why people marry? Or Jesus had brothers and sisters? No.
For even his brothers did not believe in him. John 5:7 Who did not believe in him?
Who went up to the feast without him? John 7:8-10
Your difficulty stems from failing to recognize that Joseph and Mary's marriage was not ordinary in that its teleological end was not procreation, but rather to point to the Kingdom of God. Since they were in the presence of the Most High as the parents of the Incarnate Son of God, their life of continence, like that of their Son's, points to the heavenly Kingdom, as opposed to an earthly and carnal one.
Once again, there is no Scripture supporting this idea that Jesus had uterine siblings.
