Not a chapter, schrift poll

If Riku gave a schrift to these characters and others what schrift would they recieve? I would like some ideas.

Shion (thinking kyoka unless thers another idea for a name)

Sakura (shuna)

Onyx or shinrabansho or hokuto (Blanc) (unless someone has another idea for a name, open to suggestions in the form of comments)

 Marluxia (violet) 

Jaune (name for later)
