The teleportation stuff in Ratchet and Clank: Rift Apart I'm pretty sure it's entirely dependent on the SSD.
I'd say GoW Ragnarok probably could run on the PS4 (but it'll look insane on PS5), but whether they'll release probably depends on its release date. Whenever it's released if demand for PS5 is still through the roof/largely above supply, I think it'll be worth it for them to release on PS4 as well. If people can easily grab a PS5, no one will play it on PS4 (Miles Morales proves that the enthusiast crowd would rather wait for a couple of months and play the superior version).
In all the games on the list, none can be compared to GodFall. Reviews and sales were mediocre, it's not first party, not a game that'll push people to buy hardware.
