No not necessarily, I have a betta fish and it lives without a filter and its been 1 or 2 months now. A Beta fish can live without a filter because of a labyrinth in it's lungs that allows it to breath surface air. However a heater is required to maintain the water temperature at between 75-80 degrees, betas can live without it, but they don't live as long. A heater will maintain a healthy Beta better than a filter. But if you have an aquarium with other fish. You need a filter for the other fish.
Betta are airbreathers. So long as the ammonia and nitrates are okay, you don't need filters on a Betta tank.
Betta fish do not enjoy currents that come from filters. You could put in a filter but I would recommend not to. Also, Heaters are unnecessary as long as you keep the water 70-80 degrees.
It is best that all fish have a filter besides Betta fish. Betta fish don't need filters cause the filter pushes them over with their big fins. Goldfish should have a filter on there tank because they are often overfed. If you have a filter you won't have to change the water as often. The only fish that shouldn't have a filer in captivity are Betta fish.
yes

Yes.
other Betta fish and the bigger fish.
Betta fish do not eat fish.
No betta fish are carnivores.
Well, if you love your Betta fish, then it should live by itself. But if you add another Betta to your current Betta fish's tank, then they will start a fight because Betta Fish are Siamese fighting fish and if one Betta is in contact of another Betta, the possible reason would be a fight between them two.
A betta is a fish of the species Betta, especially Betta splendens, commonly known as the Siamese fighting fish.
A Betta fish generally needs a minimum of 2.5 gallons of water in its tank to thrive. It is important to provide adequate space, filtration, and water quality for the well-being of the Betta fish.
