your AFM file is cp1251-encoded, so the correct name for it is
pmnr6w but not pmnr7k

please revert definitions of xheight, etc in cyrillic.mtx to original
definitions, and add the line "\unfakable{cedilla}"

the errors "Missing number, treated as zero." occur as the result of
commands like \height{...} where "..." is some latin letter. That
happens because you re-encoded the font to OT2 encoding, and as a
result there are no latin letters in the default encoding - they were
"notglyphs", and commands such as \height{...} work only for "real"
glyphs.

  REQUEST TO FONTINST DEVELOPERS:

  does it make sense to change commands such as \height to look first
  for "real" glyph, and if it's not found, try to extract the info
  from the "notglyph"?

The following works for me (with the above change to cyrillic.mtx re
unfakable cedilla):

\input fontinst.sty
% the next two files and cyrillic.mtx are from the t2 package
\input fnstcorr
\input cyralias
\installfonts
\resetint{minimumkern}{4}
\installfont{pmnr7k}{pmnr6w,cyrillic}{OT2}{OT2}{pmnx}{m}{n}{}
\endinstallfonts
\bye

Best,
