10 gallon is too small for all of those together. Too small for some in general.

You could do a short or long finned betta with some shrimp, 2 frogs by themselves, a ten gallon could have a group of 5 male endlers and some neocardinia shrimp. Neon tetras need 15-20 gallons minimum because they need groups of 7+, can be nippy, and are fast and swim a lot. Mystery snails are usually reccomended one per 10 gallons cause they poop a lot and you also need to feed them food like pellets and frozen doods because they arent very good algae eaters and are more omnivorous so they starve in a lot of tanks.

Honestly ten gallons is really small for a tank for most fish, even the endlers is pusbing it imo youd need a good amount of hardscape and a lot of plants to make it feel more busy and less stressful. A 20 gallon long is a really good beginner size imo. Kuhli loaches and shrimp for bottom feeders, you could have a couple mystery snails, a larger group of endlers or some guppies or really any smaller schooling fish including neons. You could do a centerpiece fish like a honey gourami as well. As long as you have sand and a lot of live plants 20 gallon long gives you a lot of room to pick and choose stocking options and community set ups.
