Although KL lacks proof if you want to know more about those in the order then here,
""Luxord - He uses cards for his attacks (throwing them for physical attacks, or using them psychologically for mental attacks?). He seems the oldest of the group. He has an aura of manipulation." (Luxord's profile)
"Luxord appears in the Pirates of the Caribbean world. Not much is known about him, but from the picture he seems to use cards. He asks to parley with Jack and Sora. He seems to lay deep and manipulative plans. Will he attack not physically, but mentally?" (Main part after the "Check")
"If you're requested to parley, you have to go with the courage to face death." (Luxord and the gang picture)

"Axel - Number 8. He uses strangely shaped blades and fire to fight. He's a member of the group, but he seems to have a different motive." (Axel's KH2 profile)
"Demix - Number 9. He uses a sitar-like weapon to fight. He doesn't seem to care much about the group's goals, and is often too lazy to finish things." (Demix's profile)
"Vexen - Number 4. He uses a big shield and water to fight. He stays calm and uses reason." (Vexen's profile)
"Axel - Appears in KHCOM too. He seemed to have died." (Axel's KHCOM profile)

"Larxene - Number 12. The only woman, she uses throwing knives and lightning to attack." (Larxene's profile)
"The common things in the group are that they all have numbers, they all wear black hooded coats, and they control the white creatures. They each have some elemental power. There appears to be 13 members, but who are the other 4?" (First box, with the Axel picture)
"The Nobodies that aren't Heartless - In KHII, other than the Heartless, there are Nobodies. They seem to be fully controlled by XIII. They seem to be enemies that need to be watched." (Box with the Nobodies picture)
"The Goal is Kingdom Hearts - From Xaldin's words, the group is trying to obtain "Kingdom Hearts" and become "complete beings". In KHCOM, they called themselves "people without names". What does this mean?" (Box with Xaldin saying something)
"The red man, Diz - Is he a member of XIII, or is he a new ally? This is all that's known of the enigmatic man, Diz. In KHCOM, he helped out the King and Riku... What is his true form and motive?" (Box with Diz and XIII member)"
