Yes, most freshwater fish need a air stone in their tank. And even if they don't need one it will improve the fishes health.

For a freshwater tank, its safe to add fish after the the ammonia, nitrite, and nitrate levels are safe for fish. Ammonia and nitrite should be at 0 ppm and nitrate levels should be very low, under 50 ppm. You should also make sure that other parameters are safe for the species of fish that will be living in the tank.
No, clown fish are marine fish and tetra and guppies are freshwater fish.
If you have seen a miniature freshwater dolphin fish, you likely saw an elephant nose fish. This is an African freshwater elephant fish that is popular in many aquariums.
Certain freshwater fish can survive saltwater conditions; examples are black mollies, mono's and scats. All of these fish aren't truly freshwater or saltwater, they are Brackish. Brackish is between freshwater and saltwater, and so these fish are highly adaptable.
A fish can disappear from a tank if it jumps out, is eaten by another fish, or if it dies and decomposes quickly.
