This page is a list of all the members of the squad known by either name or distinctive appearance. Obviously we have Vueko, Belaf, Wazukyan, Irumyuui and Pakkoyan. You know them already. These are the other ones.
Ajapoka
Ajapoka is a large and strong member of the squad often seen hefting equipment and wielding weapons. Although Irumyuui is said to be quite shy of strangers, she doesn't hesitate to run to and interact with Ajapoka when trying to warn the squad of the curse, so he may have seemed like a nice guy to her. :) Belaf calls on him to take a sample of the material at the watering hole. His form in the village may reflect valuing strength and physical prowess. Along with Pakkoyan, Ajapoka is among the villagers who try to somewhat resist Faputa's attack, and Ajapoka is then attacked by the balancing due to striking Enbelietz during the confusion (he may die at this point, this is unclear to me.)
Gaume
Along with Pakkoyan and Ajapoka, Gaume was one of the members to have their human and narehate forms spotlighted and juxtaposed in a shot in the anime.
He's also one of the first Ganja to line up at the rim of the abyss after they climb it, in the anime version of the scene. His villager form seems to value collecting items useful for delving. Gaume was has an interesting nose shape.
Eilu
The unlucky last Ganja to pass away of Abyss-related causes before the remaining members were preserved inside the village. After Eilu, all the Ganja who were still alive went on to join the village and live for one hundred and fifty peaceful years (unless killed in a Luring i guess) pursuing their happiness and enjoying ideal forms. (Notable exceptions for...well, you know which ones were exceptions.) Anyway, this is Eilu.
Haone
This member's name was revealed by Tsukushi on twitter due to interest from fans, particularly after the devoted creation of fanart by one artist. Haone has silver-blue hair that is notably long compared to most squad members, and very distinct cheek tattoos that resemble Reg's marks and the 'coming of age' marks of Irumyuui's village (that is, the marks of residents of the Golden City. Although Ganja knew nothing of the Abyss tribe before arriving, is it possible that they still somehow became aware of this kind of mark in their research, and Haone got them an aspirational symbol of her determination to reach the Golden City? We also know there are other civilizations with some cultural exchange or link to the abyss tribe because that is how Belaf was able to learn similar regional languages before arriving -- could Haone's culture somehow be linked to the culture of the Abyss tribe?
Goggles girl
Although many members of Ganja have things on their heads and hats which may be goggles, this blue-green-haired woman is the only one seen actually wearing them on her face. She also has a couple lines of her own in both anime and manga. In the manga panel where she wears her goggles, she says "it was really here...!" about the Golden City. In the anime she exclaims "Belaf!" during his transformation scene. In the anime, she is also seen supporting a weak companion during that scene.
Redhead girl
She wears a brooch to close her mantle, similar to Wazukyan. Along with Pakkoyan, she was one of the squad members to interact with the elevator hollow on their trip down.
Older guy
Rugged guy
Swirl-haired girl
This member speaks when the squad finds the hermit rat and is known to have survived until the founding of the village. She has interesting swirls of hair.
Shamashura
Has a fever on the boat. No other information.
Shurekaka
Has an extremely interesting narehate form that consists of multiple birdlike creatures with a lense or eye on the front of each one. Not seen as a human, but present in the scehes of Faputa's birth, so we know they were Ganja. One of the villagers who feeds themselves to Faputa (though it may only have been one or some of their bodies). The full-circle feeling of that scene is enhanced by knowing at least one of the villagers doing it was among the original eaters of Faputa's siblings.
Pigimuu
I'm not personally of the opinion that Pigimuu was a member of the Ganja squad. She has a distinct style of dress that doesn't really have the recurring motifs seen in the squad's dress. Her Narehate form also doesn't appear in the handful of panels that feature the transformed Ganja and no other villagers (although this by itself wouldn't rule her out from having been there...a single chorizo is pretty missable). She is not identifiable in any of the group shots in the anime of the group members who reached the abyss, the way the distinct background characters above are, and I think they would have used her design if it applied. Finally, there's the lack of her inclusion on the blue-ray cover where Tsukushi chose to showcase the other particularly distinct 'Ganja girls' -- because of the care put into the sketch page of her human design, Pigimuu would definitely quality as a Ganja girl with a lot of care put in, if she were Ganja. However, some people do see her as a member of the squad, so here she is just in case.
