Code Geass past R2 Ep 25 question *SPOILER*

Well no idea if this was all discussed some time ago, but I just finished watching the series since I took a break since ep 17 came out. Now as many know the idea that Lulu is dead is an iffy subject and some believe that he was the horse driver with C.C. at the very end because of the way she was talking. As well there was an idea of the origami having some meaning, however I have a few problems. I like to think that he is still alive because I loved him as a character but the picture of the wedding of Ougi and the chick had what looked like the princess which is dead (since the first season)

look at the female in the bottom right corner, can anyone explain to me who that is?
As well the idea that Lulu is the horse driver kind of dashed for me when I saw this close up

looks like he has a white beard. But I shall believe that 2 geass eyes means the final stage and immortality.

As for the first picture;
That looks like the Princess, I don't have a confirmation on who that is .. (interesting picture btw)
& for number two, I'm pretty sure Lelouch did die because Nunnally was there when he died, so I think thats just a random person (C.C is talking to herself/spirit?). Of course, my assumption could be wrong...

This is why I love Code Geass.. keeps you thinking with twists and turns! :D
