There're no dark chip in MGM BTNW6

No.
you can't
Shadow Fire? No idea why you'd want that, but to get Shadow, use an Invis or Mole chip EVERY SINGLE BATTLE. As for Fire, just cross your fingers. It's ENTIRELY random. Using fire chips will NOT make you get a fire style.
DarkMan is located in Secret Area 1 and is available only after Alpha has been defeated. You may need the hammer from Undernet 7 to reach his door; if not, it's still a pretty handy item to have. To open his door, you will need 140 standard chips, whether you like that or not, so get jiggy with it.
you can't. Dark aura can only be gotten in megaman battle network 3 BLUE. You get it by doing all the time trials in secret net. In WHITE, you get the Serenade chip.
Yes they are really good. There are many different kinds like dark chocolate chips, white chocolate chips, or even mint chocolate chips!!
Only in Blue, and a reward for successfully completing the Serenade Time Trials. These will be available after you defeat Serenade.
Life Aura can be found on the Scuttle viruses in the Secret Area (repels attacks < 200 dmg), and Dark Aura is not available in White. I believe Dream Aura is a combo, not a chip (Dark Aura + Sanctuary, maybe?).
