1. Jinbei is practically one now, it just won't be official until the end of the arc. Out of the remaining three, Carrot is the most likely. However, Pedro has been foreshadowed to have a future role in the story. This new age/era that he keeps referring to, at the very least he has to see the Straw Hats to it. Doesn't necessarily mean he will join the crew, but he is definitely an ally they will be seeing again.

2. Defeating a Yonko alone does not make you one. Blackbeard was not crowned a Yonko the instant he killed Whitebeard, but rather once he took over all his previous territory AND THEN defeated what remained of his crew (which was basically everyone except WB and Ace). Your reputation does not make you a Yonko, it is your influence over the world. Unless Luffy officially establishes territory, and crew structure outside of his main 9, it's just something that's not going to ever happen. As other people have pointed out, it's also not really a title that he's after.

3. He has a lot of influence, but losing his position as a Shichibukai, and thus his impunity with the WG, would absolutely cripple him. The charade he's putting on strength-wise can only go so far. His position as a Shichibukai was a handout, doesn't quite work that way with becoming a Yonko. He does have a future role in the story as well though, and I wouldn't be surprised in the least if it turns out to be a big one.

4. I'm sure Crocodile is probably involved in the underworld - as someone who re-entered the New World before the timeskip, its one of the easiest ways to remain incognito after his escape from Impel Down. 2 years is plenty of time for him to build up some influence, and possibly another organization like Baroque Works. I don't think it's likely that we'd see him, but your question was 'can' they, so technically it is in the realm of possibility. There's nothing definitely saying that he couldn't be.

5. Not sure why they'd do that. As of now the Straw Hats have no reason to go the Reverie, and the issues in Wano are much more pressing. Kaido knows Jack was supposed to go to Zou to retrieve the samurai, so him losing contact on that specific mission means that Kaido will be taking action against the Minks sometime soon. Going to the Reverie would be practically abandoning their new allies.

6. I'd have to guess somewhere in the 20's. It's been confirmed that Wano is for sure happening this year, so assuming its late like November-December, that's about how many chapters are left between that point. Oda generally takes a break every 3-4 chapters, so that's me figuring a rate of 3 chapters/month, not 4. Big Mom hasn't really been set up as a villain who's going down this arc. We still know next to nothing of her backstory, or any backstory of the major players in her crew, so it just doesn't fit Oda's style for her to go down and we never see her again. It also doesn't make a ton of sense for a Yonko to actually go down in that length of time. It saddens me, I REALLY wanted at least some kind of confrontation.
