Nick is, quite fittingly, Zeus the upper-god.
I would be Poseidon, god of the sea.
Erin is probabely Hephaestus, god of fire.
Ben could be Hermes (looks like some telecommunication device, you can use it to tap somebody on the shoulder from very far away...)
Analisa can take her pick from the available godesses: Hera, Demeter, Artemis (godess of the hunt, so I'm guessing that's the red figure on the bottom row), Athena, Aphrodite or Hestia.
Derek might be Ares
Dave could be Hades (since he's down below) or Dionysus
And that leaves Apollo for Jean-Louis
Well, I didnt really ponder the attributions, I just stuck the names on..But now that you mention it:
Right for Nick as Zeus
Right for you Hans as Posseidon . The Low contries and the sea and all that... besides I always thought all Dutchmen were green?
Right on Erin as Fire (didnt he do a map about nuclear china?)
Analisa is probably Athena, Godess of Wisdom (why not?) could not be Aphrodite nor Artemis who are to the left
Dave however would be He-man Ares (wild guess about Dave!)
Derek would be talkative Hermes (the caduceus)
Ben, Luck of the draw, got to be the Hunk sun-god Apollo.
and me, I just put myself on the old fart. whoever he is
