Out of curiosity, how many Rider Drivers can be used by ANYONE?

I know the Birth driver and Diend's gun can be used by basically just anyone who has the things to transform but I havent seen EVERY show so I don't know how many there are total. I think the "LostDriver" in W too so long as you have a GaiaMemory, and I dont think they ever actually say the Fourze driver needs a specific kind of person to use it too, right? Oh, the Kaixa driver as well So long as you dont mind dying afterwards
