I'm not that sure if you can trade, but you can transfer.
Yes.
You can't trade Pokemon olny put Pokemon in Pokemon white and black's pal park and you can't return it back.
You cannot find Heatran in Pokemon White. But if you have it in Diamond, Pearl, or Platinum you can simply trade it.
You have to wait until you beat Pokemon Black/White and obtain the National Dex before you are able to transfer Pokemon from Diamond and Pearl.
you can send Pokemon from diamond to white, but not vice versa. its kinda like with diamond and ruby/sapphire/emerald. hope this helps :D
No, but you can transfer/trade Pokemon from Diamond to White.

No, you cannot since Pokemon White has newer Pokemon

You have to trade it from platinum, diamond or pearl
Yes.

You cannot trade between the new games of Pokémon Black and Pokémon White and the previous games of Pokémon Diamond and Pokémon Pearl and there is no way for you to trade Pokémon from "Pokémon Black or Pokémon White" over to Pokémon Diamond or Pokémon Pearl. But you can transfer any Pokemon from the old ds games TO black or white .
First you have to migrate the Pokemon to diamond(have to beat elite 4) Then you trade the Pokemon to Pokemon white
You cannot find Heatran in Pokemon White. But if you have it in Diamond, Pearl, or Platinum you can simply trade it.
