It depends on the type of benefits he is receiving: SSI or SSDI. Three possibilities:
Nothing for children from SSA if SSI.
Nothing from SSA for SSDI if his earnings during his work career aren't enough.
Finally, for SSDI benefits SSA will pay children provided there are funds available based upon the disabled father's wages during his working career. If so, that amount ($X) will be divided by the number of children. From your description, if I understand it, each child would receive $X/4
