If Quirrell and Harry are both copies of the original Riddle, the original Riddle had no reason to prefer Quirrell’s life to Harry’s life.
By this reasoning, 2 Horcruxes is as many as 7.
Quirrell may not be aware of this, because he was magically brainwashed. This is the power he knows not, the power that will cost him his life at the end. He is actually magically forbidden from killing Harry.
This seems possible. (The other details, as always, seem to reduce the probability.)
