Yeah, I actually researched a tiny bit on how Jedi address each other formally. Generally what I found was this:

X being their name, of course...

Non-Jedi to any Jedi: Jedi Master X / Master Jedi X
Jedi to Padawan: Padawan X
Jedi/Padawan to Master Jedi: Master X
Jedi to any Jedi mentoring a Padawan (even a Knight): Master X

The only one that doesn't seem to be agreed upon is Master to Knight. Some say Knight X, some say Master X.

Informally, pretty much every interaction is just X, with the exception of Padawans, who refer to all higher ranks as Master or Master X. Friends of different ranks (Obi-Wan and Anakin for example) will just use X. 

Personally I think Knight X sounds weird, and I didn't know if Lenik was her Padawan. Regardless, I'll use Master X.
