Yes, you can battle Giovanni in Pokémon SoulSilver but you need to have the Celebi that was distributed for a limited time which is no longer available.
You can battle Giovanni but you can only battle Giovanni with the event Celebi that was distributed at Gamestop retail stores for a limited time which is no longer available.
You cannot battle Giovanni in Pokemon HeartGold and SoulSilver through normal game play. The eighth gym is run by Blue, not Giovanni, in these Pokemon versions. However, if you obtained a Celebi via a Nintendo Wi-Fi event (which has long since passed) and go to the Celebi Shrine in the Ilex Forest, the Celebi will take you through time, and you will eventually battle Giovanni.
You cannot battle between a Pokemon Black game and a Pokemon Soulsilver game.
You actually do NOT battle him in this game. This is because the Team Rocket you are battling is composed of ex-members that are desperately trying to find Giovanni himself and restart Team Rocket. But, you thwart their plans before they get the chance.
No.
I'm guessing you mean Giovanni? Giovanni does not appear in the storyline of HGSS, however through a special event Celebi (not yet available in the US) you can go to the Ilex forest and travel back in time where you will be able to battle a young Giovanni.
You can only find him thriugh the special celebi event.
