Sento actually is completely confirmed to have his memories back permanently at the end of Heisei Generation Forever. He talks with Sogo in the standard Zi-O world in the final scene and clearly still remembers everything.

Most of the past Riders in Zi-O actually got flowers after their two episodes, like Ex-Aid's actors, but a few didn't.

I've now actually found a picture of Agito with flowers though (it was only on the official twitter, not official website), so that one is out or at least unconfirmed.
