Is it permissible for a mother to give her daughter a sum of money without her brother, knowing that the daughter is not yet married while her brother is married and stable, and is this considered discrimination in gifting?

Justice among children in gifts and endowments is obligatory, unless some children have a special need that necessitates preferring them to the extent of their need.

Accordingly, it is not permissible for a mother to specify money for her daughter over her married son as a gift, for the daughter's unmarried status is not a justification for preferring her in the endowment. However, if she marries, she may spend on her marriage what she needs in a reasonable manner.
