No. Generation V Pokemon are only available in generation V games.
Sorry, you can't. You can migrate Pokemon with two DS's
Yes you can trade Pokemon from Pokemon Leaf Green to Pokemon Battle Revolution.
Yes, the main storyline Generation V games are Pokemon Black, White, Black 2, and White 2. The side games in Generation V are Pokemon Rumble U, Pokemon Mystery Dungeon: Gates to Infinity, Pokemon Conquest, PokePark 2: Wonders Beyond, Pokemon Rumble Blast, Learn with Pokemon: Typing Adventure, and Pokemon Dream Radar. The applications during the time of Generation V are Pokedex 3d and Pokedex 3D Pro. In Japan, Black and White were released in September 18th, 2010, which were the ones to start Generation V primarily.
No they don't
If you are playing a game that was made before Generation V, then your Pokemon will lose one HP for every four steps. In Generation V and after, poisoned Pokemon no longer get damaged outside of battle.
There are 5 regions. Generation I: Kanto Generation II: Johto Generation III: Hoenn Generation IV: Sinnoh Generation V: Unova
Rock Climb. It's HM08 in Generation IV, but just a normal move in Generation V.
Zoroark is a generation V pokemon, so it doesn't exist in Soul Silver.
I doubt there will be another one. HeartGold and SoulSilver are part of the generation IV pokemon games, and right now the most recent gen is generation V
No, Pokemon Selector only allows Japanese Generation V pokemon from #001(Bulbasaur)-#646(Kyurem). Keldeo is #647.
Chronologically, Unova is the last region as of Generation V. I have to disagree with you on that. There is talk that a new region called the Outpherm region will be the sixth generation of pokemon
