Mainly 100% removal from Ukraine (not unreasonable, but also not going happen without Ukraine doing much better on offense) and a shit ton of reparations for all the damage done and people killed (this is never going to happen).
IMHO The most likely scenario is Russia keeps 50 to 80% on land they've already captured and Ukraine agrees not to join NATO and the war stops. Keep in mind much of the land that they're currently fighting over will be useless for a generation due to all the mines and shells shot into it. (Maybe "useless" is too strong, but it will take a lot of work to make it safe for living and farming.)
