You cannot catch more than one Mewtwo. The only way to have more than one is through trading with someone else with the game.
Probably Mewtwo, because you catch Ho-oh at level 40, and catch Mewtwo at level 70. Mewtwo is stronger, and a more powerful pokemon. Ho-oh won't be enough to take on Red, unless you train it.
NO more unless you have not like caght zapdos.
you can get mewtwo more than once if you get it in firered or leafgreen and trade it via pal park
Zapos, Moltres, Airticuno, Mewtwo, mew, ceibi, raliko, and more I don't remember it all

As you may know, Masterball is the best ball. I have both yellow, silver and gold. After I got the Masterball in either silver or gold, I traded with yellow. By making a pokemon hold the Masterball you trade it and in yellow you can clone it to have more of the best ball in the world. I would guess that Masterball is a lot easier to use when catching Mewtwo that a pokeball.
The pokemon Mewtwo is so rare because, well, for one, he's a legendary pokemon, so there is only one. He is the most qwell- known legendary and has had the most hype about him, so everyone wants to catch him but there is supposedly only one, which makes him all the more rare.
Beat the elite four and get mewtwo
You can't. However, with 2 Transfer Paks, Pokemon Staduim 2, Yellow, Red, or Blue Version, and an N64 (or more simply 2 games, 2 game boys, and a connection wire) you can trade a Mewtwo (and duplicate it if you want) to Crystal Version.
