even more good news. All 5 are alive and active this morning when I turned on the light. The nitrite was .5 ppm. I'll likely continue to do 40% water changes to make sure that these stay alive. I don't want Ana to get a complex about fish dying when they come to our aquarium

For reference:
Toxic/lethal levels for fish:
Ammonia: 0.17 ppm at pH 8.5 (highly pH dependent. Higher pH means lower lethal levels for ammonia).
Nitrite: 10-20 ppm
Nitrate: 50 ppm

I am unsure which killed the other fish as both nitrite and nitrate levels were about or above the lethal levels that you listed.
