any multiplayer games in one ds?

any multiplayer games that has 1-8 players in one ds? example: QuickSpot

Probably Mario Party DS.
Usually works out well, and I know I had the monopoly rom for SNES on my PSP for a while, so If you use an emulator you can do that too.

i mean like passing a single ds from person to person

worms ^^

Advance wars DS might support 8, but I believe it's only 4.

advance wars is only 1 to 4 player but bomber man & bomber man story can surport 1 to 8 players by sending to friends that is close (please note that is with 1 game card only)

I dont know, i guess Mario Kart?if not, Mario Party..

Big Brain Academy, or Brain Age.
