"Cool" --> Not intended to be sexy but to be kind of tomboyish and fun. (Mori, Towa, Subaru, Fubuki...etc)
"Cute" --> Star of the show, they are cute and usually have star potential (Gura, Miko, Watame, Nene....etc)
"Passion" --> Sometimes sexy and mature, but often they are just motivated people intended to bring out the strong feelings of the viewer (Fauna, Marine, Lamy, Chloe....etc)
