Thundurus cannot be in found in Pokémon White 2. However there are 2 ways to putting Thundurus in White 2, 1 of which is by arranging a trade for a Thundurus with another player and the other option is to use the Nintendo 3DS eShop application called Dream Radar in order to capture Thundurus and then you can use the Dream Radar to send the captured Thundurus over to your Black 2 or White 2 game.

No you can't. sorry guys. you get thundurous in Pokemon white. you can trade from each other. but other than that you cant get tornadus in Pokemon white.
Yes
You cannot find it in white 2

You can only get them in the Black & White, Black 2 & White 2.
A trade is required from white or white 2 where it can be caught
Victini can be a mystery gift, zekrom can be only in white unless you trade with someone, Reshiram you should know where to find him you can only face N on team plasma until you catch him, Colbalion you can find him in Mistailation Cave flash is recommended, Terrakion can be found at victory road, Virizion can be found at pinwheel forest, Kyyrem can be found at giant chasm, Thundurous can only be in Pokemon white you can trade with someone else, Tornadus is a roaming Pokemon just like thundurous but its only in black, Landourous can be found at abundant shrine but you need tornadus and thundurous with you, the last three are events and unknown of when it happens and where.
You cannot find Mewtwo in Pokémon Black, White, Black 2 and White 2 so you will have to trade for 1 or you will have to transfer it from a previous game.
You can only find a Magma Stone in Pokemon Black 2, White 2, Pokemon Diamond, Pearl, and Platinum. It is not available in Pokemon Black and White.
Trade with someone who has Black 2 or White 2, or transfer it from a Generation IV game.
In Pokemon White you'd have to trade with someone who got it in Black/White 2
