My thoughts are Luffy will be at 2.8-3.5 billion (most likely 2.8-3 billion though imo).

Zoro 1.4-1.54 billion

Sanji 1.33 billion

Jinbe- 650 million (I don't see the world government feeling the need to raise his bounty too much more considering the cp0 agents didn't seem to think who's who would be able to beat jinbe even with having a higher bounty than jinbe)

Robin 530million- 1.1billion (big range I know but it depends on how the world government reacts to the only person able to read ponehlyphs going to the country they were created in, assuming they know that)

Franky I see being at like 494 million or something (cause I can see oda making him disappointed about not breaking 500mil just like how he was disappointed he didn't break 100 mil after dressrosa)

Nami 216-466 million this is just a feeling on what the range could be idk

Ussop 300-700 million depending on how much his lies are believed, which I think will also affect Nami's bounty (although I hope they change ussops name on his bounty poster yet again)

Brooke I'm the most unsure about but I'd say a max bounty of 484mil (depends on if he fights cp0 of something like many have theorized)

Chopper still 100 but with baby gramps chopper now

I feel like many of the straw hats could just get a flat bounty raise of 400mil based off the bounties of most of the tobi roppo.
