According to your aquarium info, you have 1.0 of
ammonia. You'd have to detoxify the ammonia with a bottle of prime before it's safe to add more fishes.
Your stocking list is okay but I'd suggest adding one more neon. I don't know about the loach either so wait for another member with experience for the loach. IMO, you don't have enough room for the kribs unless you keep up with daily water changes and you have a good filter.
Try this stocking list, my suggestion.
6 Neon Tetras
6 Skunk Cories
3 Fancy Guppies (all males)
Best of luck!
