As HanyuuChan said, sacrifices aren't allowed. Only the people who survive to the end (10th twilight that is) can go to the Golden Land. Not sure if there's a maximum though.
EP 1 - Battler, Jessica, George and Maria went. Well the last three did, since Battler denied going.
EP 2 - Battler, Kinzo, Genji, Rosa and Maria went. Again, Battler refused to go.
As for EP 3...well I won't say until that arc ends
