Ooooh, I don't remember seeing this question on the forum before, which is suprising. It's an interesting one to think about.

We know Lelouch, Suzaku, CC, Lloyd, Cecil, Jerimiah, Sayoko, and Nina were the ones directly involved with the Zero Requiem, so of course they'd know...I think.

As for those not already involed in the plan...

Kallen and Toudoh had a short exchange when Lelouch died, so I think that's a statement that they know. Kaguya may have had an off screen conversation with CC during the last battle over Mt Fuji. Nunnally likely knows likely through intuition and through recognising his hand structure from when she was blind. Other than that, I got nothing...
