Haven't you answered the question yourself? A little over five, just over four, slightly more than twelve etc .... Almost five, just under six, etc ... All these expressions seem fine. As Logan said in his comment a while ago, we're a bit mystified here as to what you're asking.

Unless someone who speaks both German and English chimes in, I think we're gonna need some more information here. Zahl is a number, right? I still can't figure out what this may be.
