It depends on how many otos and shrimp. The inch rule is a loose guideline. You also have to take into account territoriality and bioload. If you put, say, 3 otos and 2 shrimp in the 10g with 1 betta, you could safely add 3 cories OR 6 neons. By following the stocking suggestions in several of my aquarium books, I was able to successfully stock my 10g with 10 neons, 4 cories, and 1 betta, with 2 platies to be added soon. This is the stocking list I loosely followed:
101 Best Tropical Fishes by Kathleen Wood
10 gallon Quiet Amazon Pool Stocking List
Top Swimmers: 3 marbled hatchetfish
Midwater Swimmers: 12 neon tetras
Bottom Swimmers: 3 panda corydoras, 1 clown pleco
Your tank really should be cycled before you stock this much though and you need to do 25-40% weekly
Here's another 10g stocking list from a different book, Freshwater Aquariums by David Boruchowitz
5 zebra danios
2 cherry barbs
3 cory cats
Note that the more herbivore/omnivores you have, the more you can stock because they have a smaller bioload than carnivores.
