Not all colors match exactly this is based off of my own recollection. I watch a lot of power rangers and with my brother when he was young. Will be going in order of when we see them in SIFAS.
Up First is Ayumu, Pink. She takes up the leadership role as she along with Yu took initiative to gather Niji together. She discovers her confidence as the series progesses. As such the Pink Time Force Ranger was known to take initiative as a leader quite often.
Next is Kasumi, Yellow. She is known for her high energy and go to attitude. She clashes with other members at times, but sees them all as precious friends. For that we have the Yellow Mega Force Ranger, also had a go to attitude but cared for her team and their well being.
Shizuku, blue. As someone who puts in a lot of effort into her acting and idol work. All in the endeavor of improving her acting. The Blue Ninja Storm Ranger was known for her efforts which was rewarded as she was choosen to become the blue ranger, her efforts bearing fruit.
Ai, orange. Known for lightening the mood with her pins, Ai has shown that she there to help people as she loves interacting with them. The White,with orange, Jungle Fury Ranger he brought some fresh air to the group in their time of need. Laid back but ready to go.
Rina, grey. A shy girl who is trying her best to improve herself. What she is trying to overcome is her overthinking, making it hard for her to express herself. The Black, think dark grey, Wild Force Ranger, while finding themselves shows how they dependable they are.
Kanata, purple. The most laid back, literally, has shown that she is still there for the group even when she has sleep on her mind. The Purple Jungle Fury Ranger uses his own method to teach his peers even when it looks like he is off somewhere else. They come first.
Emma, green. In a new land all by herself, has shown her love for idols and her friends. The Green Time Force Ranger, is also a stranger as an alien on a new planet. His team still hold him dear to them and knows that they can depend on him.
Karin, navy blue. Strong willed as she has gained confidence from her modeling. That confidence can't hide her love for Niji and her cute quirks. The Blue Thunder Storm Ranger, has the confidence, but can't hide how much he cares for his team and brother.
Setsuna, red. She was away from Niji but to gather herself and come back at full force. Has shown to take initiative and sets an example for many. The Red Samurai Ranger, was away honing her skills, that would help the team in the end.
Yu. Being what hold the group together, working in the background. Her work has garnered praise from those in and out of Niji. The Shadow SPD Ranger worked as commander for them but was known for his other accolades as well. Being a strong leader behind the scenes.
Shioriko, green. Seen as an obstacle at first comes to realize the efforts of Nijigasaki, joining them in their endeavors, learning what it mean to be part of a team. The Green Mighty Morphing Ranger went from an enemy to a great friend and team member. Green/White too.
