What is the ruling on disposing of funds from aid and gifts given to the family of a martyr, and what is the share of each of the wife, the daughter, the martyr's parents, and his siblings from it? Is it permissible for the wife to dispose of her daughter's money to complete her university education?

It is not permissible to dispose of granted funds except within the restrictions specified by the granting bodies. What was granted to the girl is hers, what was granted to you is yours, and what was granted to your husband's parents and siblings is theirs. If you need money, it is permissible for you to take from your daughter's money in a reasonable manner, but completing university education is not among the essential needs that permit taking from an orphan's money, unless it is a religious education that is obligatory upon you. You are entitled to receive a wage for fostering the child from her money if there is no one to foster her without compensation, and the wage is determined by what is customary in your country.
