Yes, the .30 Army cartridge is the commercial designation for the .30-40 Krag. Brass is still available. I would load for it with a hard-cast lead slug, though.
You can make up a slightly-short version of the .35 Winchester for your '95 from Krag brass or, better, from .405 Winchester brass: straight FL resize. This was a real bear-buster of a cartridge and actually was loaded in the commercial ROSS Rifles for a few years.
As to the .32-40, this was originally a Ballard cartridge from the 1870s that Winchester adopted and gave their own name to. It was a favourite with many of the old-timey shooters (including Harry Pope) for the 40-rod (220 yard) offhand 100-round matches that were popular a century ago. Brass is hard to find nowadays, but Lee makes the dies and they are cheap, too. I load this for a couple of friends and make them out of .30-30 brass which they don't bring back, often as not. I'm running short of .30-30 brass, of all things! The loading manuals will list several loads for this cartridge, including some almost up to .30-30 power levels. OLD guns (and yours is one) almost always respond best to a load closely approximating the original 1873 performance. You can get this by loading 17 grains of IMR-4198 with a 170-grain bullet for a .32 Special. Yes, the correct bullet diameter is .320", but running a .321" won't hurt it.
Good luck and have fun!
