Yes the first is only for 50mm lenses that fit using the internal bayonet. Note some 50mm lenses fit externally only (eg a version of the f1.1 lens)
No, all Nikon rangefinders use the same mount.
Note some Nikon rangefinder lenses lenses will still not mount to the Leica even with the 'universal" adapter as they physically interfere with the Leica focussing mechanism eg the 3.5cm f1.8
