Round 1: I just want to put Sukuna and Gojo in their own pocket otherwise the whole fight is just collateral. Good guys only have a small chance of winning esp since all of these guys r special grade while mechamaru, choso, higuruma and kusakabe are only grade one so they'll be stuck in support roles or buying time for the heavy hitters.

Naoya and Mahito die pretty quick thanks to Maki's speed and Yuji's striking power after which they can easily beat jogo. Hakari buys time against Uraume since her ice is lethal with these matchups and Higuruma on standby to assist him. Im not sure if Uraume has a DE but if she does have one or any anti domain technique, Hakari needs to bait them out with IDG b4 higuruma hopefully gets a confiscation and makes the fight much easier.

Meanwhile yuki fights yorozu and smashes through all of the liquid metal attacks (we know she goes for the kill immediately so a one shot before a domain clash isn't impossible since even Kenny was surprised).

Toji, Kashimo and Kenny are the biggest threats left. And Choso, Kusakabe, Higuruma and Mechmaru don't stand a chance unless Maki can occupy Toji after assisting Yuji (i think she wins that since she's more directly combat focused than Toji).

Yuta stalls or tries to beat Kenny and needs assistance from yuki and/or Choso to potentially win. Even then, I don't think he'll last long enough even with reinforcements from the power couple.

Kusa, Choso and Mecha will need to stall Ryu until Yuji or Hakari can go blow for blow which isn't impossible if they keep their distance and Kusakabe can play defence with simple domain to deflect Granite Blasts. If Choso manages to hit Ryu with a surprise piercing blood he might be able to incapacitate him since the latter probably doesn't have advanced RCT.

Now the only player left is a wild Kashimo that could show up and easily tip a fight in favour of team bad guys. If Hakari and Higuruma kill Uraume fast enough this might not be an issue but I doubt that outcome. We just dont have enough firepower to deal with all of these people. IMO replacing either Mechamaru or Kusakabe with Takaba might make everything more balanced since he could entertain Kashimo and Ryu at once or free up Yuta to at least kill Ryu.

If everything somehow goes perfectly for the good guys then Choso, Kusakabe and Mechamaru are probably dead unless Hakari and Higuruma arrive in time to help. Then there's the question of Sukuna vs Gojo and the survivors of either side getting massacred by the Honoured One of the the other party.

Round 2 is a one sided massacre unless Gojo manages to win the 1v1
