Here’s what I think will happen for the rest of the arc:
Number 6 shows up on the live floor (he was supposed to be around there for a while anyways, based on the cameo of an unrevealed Number we saw a while ago). Chopper beats him fairly easily using his current powers, and then the final and strongest Numbers, Numbers 1, 2, and 3 show up. Chopper is stronger than either one individually, but can’t handle all 3 at once. Zoro and Sanji can’t help because they have their hands full, and Marco is still recovering. Chopper uses the Ice Oni virus to temporarily buff himself. This will give Chopper the strength to win, and he injects himself with the cure to return to normal. This will be a new powerup for Chopper.
Raizo beats Fukurokuju.
Perospero pulls a dirty trick to beat Sulong Neko, and Carrot is the one who gets to finish off Pero, who is very weakened at this point.
Denjiro does something relating to Hiyori and/or Orochi
Sulong Inu has the upper hand on Hybrid Jack, but then Jack pulls out his Awakening form. It makes him either equal or slightly stronger than Sulong Inu. Either way, Jack wins eventually, either by overpowering him or Inu runs out of gas due to Sulong being very taxing, and Jack wins by outlasting him. Jack is extremely weakened afterwards and probably only at 20-25% HP. Usopp has been lying about beating two Tobi Roppo, and his lie will somewhat come true by him beating a Calamity (ranked above the Tobi Roppo, therefore “two Tobi Roppo). This will give Usopp another inflated bounty since he will get the credit for beating a Calamity, even though Inu did most of the work. I envision the fight starting off by Usopp fighting from long range, trying to keep Jack away from the live floor. Usopp will try to gradually west down Jack’s health little by little with his long range shots and traps he sets up. Of course Jack won’t take much damage, but he will still take some damage (maybe around 5% HP). Eventually Jack closes the distance between him and Usopp, and Usopp is forced to obtain a new power in order to finish off 15% HP Jack. During his “fight” with P1, Usopp commented on how he lacks the proper tools for CQC. This could be a way for Oda to confront this weakness of Usopp’s and come up with a solution. After all, Usopp will need to learn how to handle fights competently at close range if he wants to surpass his YC2 level dad and become a “brave warrior” by the end of (probably) Elbaf. I’m not sure what exactly Oda will do, but obviously it would be a pretty substantial power up. Maybe Usopp unlocks CoA, and the less distance his CoA shots have to travel, the stronger the impact (making him less weak at CQC)? Oda is also hardcore teasing Usopp’s CoC in this chapter, so maybe Usopp manages to briefly tap into Adv CoC and imbue it into his most powerful shot, with that being enough to put down the, at this point, severely battered Jack.
Sanji beats Queen and Zoro beats King. Hopefully they unlock Haki upgrades during these fights so that their Haki isn’t lagging too much behind Luffy, who has advanced versions of all 3 Haki types at this point.
Jinbe, Robin, Franky and Nami probably don’t do too much when it comes to fighting for the rest of this war. Hopefully Brook somehow gets a good fight though because he has done basically nothing but beat a Number and a few Gifters.
Luffy, Yamato, Marco, and Momo vs Kaido
Kid, Law, Drake, Apoo, Killer, and Hawkins vs Big Mom
Idk about CP0 and the B
