ELI5: if all budget proposals from the white House have been rejected, what power does the white House actually have? And who else has power?

Only Congress can enact spending bills. The president's power in that process is, he can veto any bill. 

The president proposes a budget. But it really is just a suggestion. Congress has to approve  it and is free to change it however they want. Of course if the president and Congress are controlled by the same party, they will likely see eye to eye on most of the budget. To see so much of Trump's budget proposal get shot down by a republican Congress just shows how inept this White House is.
