The font in #11 and #10 is not what we're looking for.
Entry #12 looks good, but the "jupiter" part needs more attention. I'd say that the Jupiter part of the name is slightly more important than the Projekt part.
#52 looks good, however I don't really like the "string" crossing the letters. Also I feel that the whole "string" part fits the font, but doesn't really fit the rest, maybe the way to go would be to change colored part a little bit so it better connects with the string.
