Marrying one's foster sister's sisters and neices

Q: I have a foster sister with whom I have shared milk from her mother. In my knowledge, she is like a sister to me and is mahram so I cannot marry her.

What I want to ask is that the other relations (her sisters and her neices [sister's daughters]), are they also mahram to me and I cannot marry them?

A: Yes, you can marry them.

And Allah Ta'ala (الله تعالى) knows best.
