Ah! I'm writing a fan fic covering just this.
Tomo's a cop (not in interpol yet)
Osaka's a teacher alongside Yukari & Nyamo
Yomi's the creator of a new hit manga series starring an odd, green-haired girl (

)
Sakaki is a zoo vet specializing in felines
Kagura is a gold-medalist swimmer
Chiyo is the head of Mihama Ltd., a megacorp very similar to Apple. (In this fanfic, she also has a robotic hand, but that's beside the point)
And Kaorin... I dunno. A scientist, perhaps? Haven't wrote her in yet...
