I like Adriana when pronouced Ay-dree-AH-na, Lana is okay but again I'd prefer the Ahna pronunciation. I'm not a big fan of Emil. They do go nicely together though.
I like Adriana the most... I like Lana spelled Laina or Layna...unless you want it pronounced like Lanna...then I don't like it at all. I'm not crazy about Emil, it just doesn't fit my style.
