Well, SIce can use .nms files to use names for code locations like procs etc..

Is there a way to use them with olly? Some plugin?

Greets,

softice .nms files are used for kernel mode driver (primary) and user mode application debugging. Input file formats are .dbg/.pdb and .sym files.

Its a proprietary file format with no "standard" tools/api supplement like microsofts dbghelp API. There is no use *outside* of softice.
The whole debug helper api that most user mode debugger use is centered around .dbg and (much more) .pdb file format.

Why in the world whould someone use numegas .nms files for a user mode debugger like ollydbg when .pdb (.dbg is deprecated) is the native symbol information format?

input .dbg/.pdb/.sym -> conversion -> intermediate .nms -> conversion/emulation -> debug helper api (which needs .dbg/.pdb information)
= pretty much useless.
