yes, that's what the discussion is about for quite a while now.
the first two are financial hits that probably will result in finding eachother along the way. it's quite the money, but still not really 'way out of the ballpark'.
the car really is a laugh, that's not an issue, if it was made, it'll probably already be in his driveway.
the last one probably is a bit of a thing, depending on how it's really written down on paper.
i would argue that this goes into the area of having 'too great' of influence to what mercedes wants.
after all it's Mercedes-Benz, not Hamilton F1, no matter whether he's a 'SIR'.
It's probably more the case of 'unravelling' what he really desires with the latter, and finding the writable/firmable limits/boundries of such.
After all, what Mercedes -rightfully so- doesn't want is Hamilton deciding what clothes the crew are allowed to wear and what they're allowed to eat. Again, i'm not at all claiming there is proof Hamilton fe wants everybody vegan, i do believe that it's neccesary that you don't accidentally give somebody the room to do that. And again, that 4th 'speculation' leaves room for just such a thing.
Money can be negotiated and filled in. the last part cannot. it'll be a combination of these. meanwhile, nobody has a rush, both surely will have already have a verbal agreement to race, it's just a matter of paperwork, and it's being dragged out by the media because it's essentially 'all the media has' and Lewis is a 'celebrity' right now so a moneymaker for the tabloids and clicbait articles.

"Hamilton was beating Verstappen 7-0, then the ref decided F%$& rules, next goal wins
while also sending off 4 Hamilton players to make it more interesting"
