C.C. is the only one he tells on-screen. Anyone else is just supposition.

Suzaku probably knew considering he guessed Lelouch was lying about his reasons in Turn 17. The others knowing about Requiem (Jeremiah, Sayoko, Lloyd, Cecile and Nina) might have been told the whole truth (especially Nina in that case), but Lelouch wanted everyone to hate him and didn't care about excuses so I don't think he did.

The only other that might have known is Kallen since she knew about Geass, if C.C. explained he lost control, but we have no idea. She stayed with the Black Knights against Lelouch so she might have believed him fully guilty.
