Now with the Twinkling Cures:

Kohaku Daisy/Cure Amber: I was thinking Splash Star. She would get along well with Saki, plus light would be nice for the Splash Star team.

"The wonderful orange light, Cure Amber!"

Yuriamai Sakura/Cure Floret: Probably Smile. She loves fairy tales, plus she would get along well with Miyuki, Yayoi, and Candy.

"Blooming, smiling, the flower of friendship! Cure Floret!"

Izumi Rose/Cure Sapphire: Yes! 5 Gogo. She would get along super well with Karen, plus she and Cure Aqua could team up and fight monsters together!

Has the same introduction speech.

Kohaku Hikaru/Cure Solar: Maybe Go! Princess? She wants to be a singer, and she loves her dream, so that would work. She would also encourage the others to have happiness, which might help? I don't know.

"Princess of the bolts of happiness! Cure Solar!"

Kodoku Seishin/Cure Starlight: Probably Fresh. She would get along super well with Setsuna, plus Seishin has had an intrest for dancing.

"The purple heart is the symbol of freedom! Freshly-sparkling, Cure Starlight!"
