On the player, no, it's not possible as the song could exist on multiple playlists and would not have enough room to show it.
None of the hardware shows the memory notes; this is only visible within rekordbox.
The cues are not loaded on the other deck, possibly because the same track is being loaded as an "instant double" and in the interest of playing instantly, it doesn't load the memory points / hot cues. You can manually call them.
