By trading the other starters with other players of Diamond or Pearl.
Not possible unless you use a cheating device.
No matter what game of Pokemon you play to get all the starters you have to trade with the other versions.
You can't, but you can get them all through the global trading system or gts.
You have to trade with friends to get them, or trading with someone else (it can be by using GTS too) or by having another compatible Pokemon game (another LeafGreen, or a FireRed for instance), where you can restart the game and trade the starters.
