Yes after you conquer your 5th kingdom you can catch wild pokemon. It's not really catching it's just making a link with them. This is a cup with all of the people who hate pokemon conquest. \_/
No, none of the starter pokémon appear in the wild in Pokémon LeafGreen. You'll have to trade with other games.
Tornadus, Landorous, Reshiram, Virizion, Terrakion, Cobalion, Kyurem, and Victini.
It is in the wild, anywhere. Whenever you change location (go into houses, etc) it will change place. You need to 'unlock' it before you can get it though.
latios and latias appear in random patches of grass and areas of water after you catch Rayquaza or make him faint.(after saving the world in Sootopolis.)
No you can't catch a Tepig in the wild. You have to choose it as a as a starter pokemon.
