I was a kid when the original film came out. Somehow, pre-Internet, my brother and I knew the "baddie" as Darth Vader, Dark Lord Of The Sith. For me, my older brother was the Internet, and often knew stuff from magazines and books he had read, so I may have picked up the Sith title from him.

Then there's this from the screenplay, available in countless places online:

"Revised Fourth Draft January 15, 1976

LUCASFILM LTD.

...

INTERIOR: REBEL BLOCKADE RUNNER -- MAIN HALLWAY.

The awesome, seven-foot-tall Dark Lord of the Sith makes his way into the blinding light of the main passageway."

As far as we know, the Sith did exist then (even if Lucas hadn't formally thought of them) because he injects them into the universe later on, but as for the subject of whether or not characters in the first film knew, all we have is that a small number knew about the Dark Side of the Force, but beyond that, it's bound to be conjecture.
