What is the ruling on three daughters, one son, and their mother sleeping in one room?

If each individual has a separate mattress or bed and a separate blanket, there is no harm in family members sleeping in one room, although it is better for each of the sons, daughters, and the mother to have separate rooms. If they must sleep in one room, then each individual must have their own mattress and blanket, especially if the children are adults or close to puberty.
