Are mortgage brokers subject to supervision by any federal agencies? Are they subject to Flood Ins requirements?

It depends on what part of the business you are referring too? They are not directly covered by Flood Ins. regs as they are not regulated lending institutions, but since they usually sell there loans to one, the purchasing institution would make sure that they followed the appropriate guidelines. HUD has jusidiction over them for RESPA violations and normally they are somewhat regulated by the state in which they are doing business. There is no federal agency with direct responsibility.

Mortgage brokers in Texas are regulated and licensed by the Texas Savings and Loan Department. I agree there is no federal regulator with direct supervision.

Ditto to both answers above. The key player is most likely to be the state. In theory, the Federal Trade Commission could have jurisdiction if it pursued an unfair or deceptive trade practice. But historically, the FTC has stayed as far away from RESPA as possible. And of course, FTC has nothing to do with Flood.
