Is there maybe a addon or something where I can move my player nameplate around, and move my target nameplate?
I've seen UIs where it has been like this but I can't find an addon for it and I can't find anything in the WoW interface to change this.
You can download MoveAnything which allows you to move anything that is in the default blizzard UI.
I think the OP is referring to UnitFrames. In which case there are many mods for Unitframe replacement. http://www.vranx.com/unitframes.htm
Or grab MoveAnything if you just want to move them.
