-Lucci would be properly defeated by Zoro in the first situation. It would take longer, because Sanji wouldn't piss Zoro off and force him to hit Lucci at time, that was only possible through Jinbe being there.
-Zoro wouldn't reach the Sunny at time without Jinbe throwing him, so Nusjuro would've destroyed the Sunny and possibly defeated some Strawhats.
The 2nd situation is easier to guess after 1120 because Zoro is clearly desperate about Nusjuro coming back to attack the Sunny again, he knows Nusjuro is strong. So if Jinbe wasn't there initially, before their first clash, the Sunny would be wrecked, possibly one Strawhat (or more) would be hit, getting badly hurt, then everything would be completely messed up.
