Aren't you a bit depressive today?
Not entirely.
The only time we see Janeway after the conclusion of Voyager, she's an admiral and (iirc) working at Starfleet command.
I got the impression that the majority of the Marquis didn't want to be on Voyager, nor particularly wanted to be in Starfleet either. It was a decision on the part of Chakotay. I think
initially it would have been all of their intent to reconnect with the Marquis once they returned to the alpha quadrant.
I'm sure that all the Maquis were paroled after the Dominion War.
I'm not. They were trying their hardest to restart a war between the Federation and the Cardassians for their own goals, a war that (according to Picard) cost millions of lives.
I don't think Neelix would have been unhappy in his new home, Neelix typically seem to be the type of person who was happy in their surroundings, Neelix likely would be happy almost any where he was. And if not, Neelix still had his small starship and could have ventured forth into the neighboring space.
Would Naomi enter Starfleet academy one day? Hard to say, the decision would be a decade in her future and that's a long time to a child.
Tom Paris was temporarily in Starfleet originally, his goal was a pardon for his crimes which I easily see him receiving. He could remain in Starfleet by simply making the request. Although in-spite of his (fairly) good record aboard Voyager, given his criminal record and being married to a former Marquis I wonder if he would have difficulty obtaining the needed security clearance.
Tuvok would take a sabbatical from Starfleet to reconnect with his family and consider his options. A promotion to captain and a command of his own would be easy to see.
I believe Harry
would receive his lieutenant jg pip.
Chakotay would return to his planet in the former contested territories and the life he had there, the conclusion of the Dominion War would see this world (and others like it) free from any claims by the Cardassian Union. Whether his world would remain independent, join the Federation, or pursue other options is hard to say.
Many of the Voyager crew would stay in Starfleet, but some would wish to leave the service after their experiences.
Of those who stay in Starfleet, most (imho) would never want to set foot on Voyager
ever again.
