They never appear together in any episode of the Pokémon TV Series. Groudon and Kyogre were only seen as the real things in the episodes titled "Gaining Groudon and "The Scuffle of Legends" whereas Rayquaza has shown up in nothing but movies so it hasn't been in a TV episode yet.

There will never be unless Pokemon games stop.
The only Pokemon out of the three you mentioned to evolve so far is Ash's Tepig. Ash's Tepig evolved into a Pignite in the Best Wishes episode number 077, 'Evolution by Fire!'.
Apparently Groudon, but you need to trade with ruby to be able to obtain him.
Groudon is #383 in the National Pokedex, and it is a Ground-type Pokemon.
