I think it's going to be tough to find a retail dealer with replacements for most of those. Between these two dealers, you should be able to get them all:
Bear in mind that most of those styli are no longer available from the original manufacturer, so 3rd-party replacements will have to do. LP Gear general sells quality stuff, but 3rd-party replacement styli are often a crap shoot, and rarely perform up to the level of the original manufacturer replacements. I had the school buy a few Stanton 3rd-party replacements before I retired. Seth Winner and I tried them in his studio - it took only a few minutes to determine that they were garbage.
My advice on obsolete cartridges is to replace the cartridge, rather than getting a stylus that's not up to par.

-Ortofon OM 10
-Ortofon OMB 20

I appreciate it.
