In every Digimon season there are parallels in the stories and in the characters. Juri I think is one of the very unique characters that touch in nearly everyone’s personality and group because she is a very dynamic character and changes when things change as all realistic people do. She shifts her emotions when times change to best fit when she needs and she reacts to everything differently.
Please note that I haven’t seen Frontier so I might get those wrong.

Group1: Depressed group:: Matt (season 1) Ken (season 2) Juri (season 3) Kouji (season 4)
This group is often mixed with the “bad-ass” group because there is a very fine line in between them. Juri is no by in the “bad-ass” group for that is more reserved for Ruki. The depressed group is a when one of the kids stands out more as the angst child of the group. Their angst usually hinders the whole group, occasionally leading then the path to destruction. The angst is something that shows periodically and seems to center in the character’s life. The angst is always taken away in a beautiful emotional scene.

Group 2: Girlie Group Mimi (season 2), Hikari (season 2), Juri (season3), Izumi (season 4)
Strange but the only true ‘girlie’ tends to be Mimi but they out of all the rest of the group have the most feminine traits of the group (Juri is the least). They may not be totally feminine and girlie but they are at time ladylike and such.

Group 3: The insecure group Jyouh (season 1), Iori (season 2), Juri (season 3), Tommy (season 4)
This group tends to think lowly of themselves. Although people tend to think highly of them and know they are reliable they have a tendency to reject that.

Group 4: The wan-a-bee group Takeru (season 1), Daisuke (season 2) Juri, Kenta and Hirokazu (season 3), Junpei (season 4)
They are the characters that aer always helpful but at first tend to be weaker and acts to slow them to the action. However usually in a burst of strength they will occasionally get the big group in a tight pinch.

Group 5: The dark side group: Sora (season 1), Takeru (season 2), Juri (season 3), Kouchi (season 4)
No, they are not the depressed group, their changes in personality are much more striking and perhaps even scary. They are not in a constant state of depression and it only surfaces occasionally. Their ‘dark side’ is never really explained but it there to help with character twists.

Group 6: The death involved group: Takeru (season 1), Ken (Season 2), Juri (season 3)
This group is involved with a death of a digimon, and the death of a digimon usually in only part of a contribution to a dark side and/or depressed state. They usually have other feeling of loss or death before.

Group 7: The perky group Takeru (season 1), Miyako (season 3), Juri (season 3), Izumi (season 4)
Not to be mixed with the ‘ecstatic happy-go-lucky’ group. This group usually is not the source but a healthy contributor the comic relief. They tend to look on the bright side of life, which could might as well bring them to their down fall.

Group 8: Special Items character Hikari (Season 1 and 2), Koushiro (season 1), Juri (season 3)
This is excluding Goggle Boys (hats are also excluded). These characters usually have a special item that tends to explain them. When this particular word is mentioned they tend to think of a specific character such as whistle, laptop, ect.

Group 9: Family problems Sora (season 1), Takeru (season 2), Juri (season 3), Kouji and Kouichi (season 4)
Now while many could fall in this general group I’m thinking more along the lines of fighting with families. These tend to show tension and strains in relationships in the families.
