Who's Who?

[redbrunja]

So, I was wondering if someone (or multiple someones) could help me out.

I want to know what the names mean in Saiyuki. I remember reading that Hakkai's name means "every sin but one" and Yaone's was "eight hundred mice" but what are the others? I know 'Sanzo' is a rank, but what does 'Genjyo' mean? And Gojyo and Goku?

Thanks.
