Seeing as how this is a direct Invisibles question, perhaps it would be best to discuss the attributions as they occur in the books, themselves?
As we begin the saga, V1I1, Mob is the implied leader which is said to be "air" and the yellow slip. Over the course of the first volume, we learn that Fanny is water, Robin is fire, Boy is earth, and the missing member — JohnADreams — has the attribution of spirit.
As said before, "spirit" is the white slip, and holds transformative properties for the individual, as well as for its corresponding cell. As JohnADreams steps out of the universe and vanishes, Mob is instructed to initiate a new member, Jack Frost. From there, hilarity ensues.
Robin's role as fire is barely touched upon in V1, as is Fanny's as water. Boy is shown as earth in her training of Jack in fighting styles.
At the beginning of V2I1, the Invisibles cast draws new slips for new roles. This time, Robin draws yellow and everyone defers to her as leader. Mob draws black for earth, and states his responsibilites plainly: guns, ammo, funds. Jack picks water, Fanny picks fire, and Boy is left with the white slip of spirit.
Boy thus begins her transformation as she manages to steal the Hand of Glory, defeat the Church's hidden subconscious programming, expose the duplicitousness of the "Invisibles" in other cells, percieve the Barbelith without psychic powers, and quit the team altogether. Volume 2 is the dissolution of the Invisibles cast, and Boy insitigates it.
Now, judging from everyone's actual actions in the two volumes and two roles, I would suspect that water corresponds directly to emotional connectivity -specifically to the spirit role, as Fanny reaches out to Jack early in V1, and Jack reaches out to Boy in V2.
Fire could also be significant to the role of confrontation in each cell. Robin, as fire, confronts the Blind Chessman and destroys the limitations of language by ignoring the myrmidons with the Head of John the Baptist. Fanny is most significant in V2 as the one who decieves Quimper and destroys the belief that the universe is manichaen by willingly going into the magic mirror.
