Awfully close to mehl is Bliss Pro - http://typography.net/try/?ff=27&f=149 and
boris looks like someone handtailored TheSans: http://www.fontshop.com/fonts/downloads/lucasfonts/thesans_basic/

thank you, but the "i" doesn't look like this :( that's my problem. I found so much fonts looking like this, but everytime the "i" was without serife :(

I did find the "i" in some fonts 9 but the "b" never matched up - that was the closest I could get you...
