Lester is an ancient Anglo-Saxon surname and is derived from the concatenation of an Old English tribal name "Ligore" and the Old English word ceaster meaning "Roman Town" or "Walled City".
This could be seen in the fact that he is an incredibly old character who is walled off, waiting for you in his castle.

I'm not seeing anything for Yulyana's name that isn't a plot point.
