Do the daughters' children, who died before their grandmother, inherit from their deceased grandmother's inheritance, given that she has one son and two daughters?

A daughter who dies before her father does not inherit anything from him. Her children do not inherit from their grandmother (their mother's mother) because they are considered uterine relatives (dhawu al-arham), not legal heirs. Anyone who traces their lineage through a female does not inherit, except for the children of the mother and the maternal grandmother (mother's mother). If a person dies leaving behind a son and two daughters, and no other heirs, the estate is divided among them by ta'sib (residuary inheritance) with the male receiving the equivalent of the share of two females. This means the estate is divided into four shares: two shares for the son, and one share for each daughter.
