Is there a hdd power cable with a MALE 4-pin connector that extends into one female 4 pin connector and one..?

SATA power connector? If so where can i buy one?

Probably, but most people just buy Molex to SATA power adapters. If you need more Molex 4 pin plugs, just buy some Y splitters. Any computer store worth a darn should have some of both in stock, even the chain ones.
