You could, but there is no gaurantee that they will survive long. Tetras like their water to be around 70-72 degrees and all fish love a filter. It keeps you from having to clean the take so often and the fish live longer. They do make heaters and filters specifically for fish bowls between 2 and 5 gallons. White cloud mountain minnows are probably the best fish that you could keep in a bowl without a filter or heater.

Can 4 guppies and 2 neon tetras go in a 2 gallon tank?

Yes, since Guppies and Neon Tetras are small fish (and stay small), there should be no problem with them living comfortably in a 2 gallon tank. You should add a little filter and air bubble combo to keep the water clean and aerated. Since these are tropical fish, you should also add a small heater and a thermometer. Goldfish do not need a heater but tropical fish do.

Can two tetras live in a bowl?

No fish can live successfully in a bowl. Far better you either throw the bowl away or use it as a vase. If you really want to keep fish get a reasonable sized aquarium to keep your fish in. There is a basic rule that all successfull fish keepers use and that rule is "1 inch of fish needs a minimum of 1 gallon of water" For you to keep 2 Tetras successfully you would need at least a nominal 5 gallon tank with a heater/thermostat (set at 75F), thermometer, Cycled filter, coverglass, Lights, gravel, and live plants.

Could you keep 3 red cherry shrimp 3 male guppies and 5 neon tetras in a ten gallon tank with 3 live plants a heater an ornament and a sponge filter?

Yes. If you keep up with small weekly water changes (about 25% of the tank's volume), then you should be quite alright. Having a planted tank helps filter out some of the toxins produced by fish waste so that helps. I'm also assuming you have the minimum acceptable filter capacity.
