Are the children of one's adopted father's second wife mahrams?

Q: I'm adopted by my parents. My adopted mother then breastfed me so they became my foster parents. In 2021, my mother (foster mother) passed away and my father got married to another woman. She already has three children. Are they mahraam to me? Should I have to make purdah from them? Is it permissible to marry them at the same time?

A: No, they are not mahram to you. You will have to make purdah from them.

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