Is benefiting from the father's end-of-service bonus, which was deposited in a Riba-based bank and multiplied over time, considered Riba, and what is the ruling on giving the profit as charity to a relative to perform the Hajj pilgrimage if the money is impermissible?

If the bank is usurious, the excess interest beyond the principal amount must be disposed of by spending it on the welfare of Muslims, such as aiding the poor and needy, repairing roads, and building hospitals. It is not permissible to give it to someone who would use it for Hajj as long as there are those in need of food, shelter, and similar necessities.
