I remember that show on Cartoon Network. Yeah, the five-man dynamic is common in Japanese media. It also appears in the West, though. The Hero: The main protagonist. The Lancer: The bad boy, and everything The Hero is not. The Big Guy: Kicks butt. A lot. Often dumb. Mute, too. The Smart Guy: Weaker, but ahs a brain. The Chick: The peacemaker and nurturer. Often a medic too. Often the emotional one. Usually a woman, hence the name. Sixth Ranger: Comes around later. Often used to be a bad guy, or has been secretly fighting the Emperor Evulz since before our heroes came on the air. Sixth Ranger Traitor: Like the Sixth Ranger, but evil! (Yes, I know, the name is stupid, and Sixth Column's a better name. Blame Heinlein for writing a story called Sixth Column.) YJK plays it perfectly, with Jacen as The Hero, Jaina as the Lancer, Tenel Ka as The Big Guy, Lowie as The Smart Guy, and M-TD as The Chick. (Jacen has some shades of The Chick as well.) Zekk's the Sixth Ranger, and in some of the official art, he evn looks like the Trope Namer with short hair. Relevant to this, Kyp's the Mentor, but he used to be a Sixth Ranger Traitor. Which is, oddly, the most popular of the ensemble. The bad guys have learned how to do it as well. There, they are the Big Bad, the Dragon, the Brute, the Evil Genius, and the Dark Chick, with the sixth guys being the same. There, rather than being about five, it's one guy and his four henchmen, the Japanese word for four, shi, also meaning "death".
