I've been thinking about this a lot recently and I personally think that these three make sense, and I'm not sure about what the others could be but this is what I think so far:
Saturn: Hito Hito no Mi: Model Minotaur
Demon bird dude: Tori Tori no Mi: Model Griffin (or Basilisk)
Imu: Satan fruit, don't know what it'd classify under, possibly another Hito Hito though.
