ok here are the questions/answers I thought would be useful...
Professions:
Kinsley: Minister of Magic
Harry: asked by Kinsley to head up the new Auror Department
Ron: Joined George at Weasley’s Wizarding Wheezes, which is doing very well
Hermione: began her careers at the Department for the Regulation and Control of Magical Creatures where she was instrumental in greatly improving life for house-elves. She then moved to the Department of Magical Law Enforcement where she was a progressive voice who ensured the eradication of oppressive, pro-pureblood laws.
Ginny: Spent a few years as a celebrated player for the Holyhead Harpies, she retired to have her family and to become the Senior Quidditch correspondent for the Daily Prophet
Luna: Became a very famous wizarding naturalist who discovered and classified many new species of animals, she ended up marrying a fellow naturalist Rolf
George: continued with Ron’s help Weasley’s Wizarding Wheezes and named his first born son: Fred
Neville: Herblogy professor at Hogwart’s
Percy: High-Ranking official under Kinsley
Hagrid: Still at Hogwarts
James has the marauders map, he snuck it out of Harry’s desk.
Hermione found her parents and brought them back.
Harry can no longer speak parsaltongue and is glad.
Teddy was raised by Andromeda. However, unlike Neville, who was also raised by his grandmother, Teddy had his godfather, Harry, and all his father's friends in the Order, to visit and stay with. Teddy is a Metamorphamagus like Tonks.
Harry and friends all appear on chocolate frogs, Ron said this was his finest hour.
Mr. Waesley fixed Sirius’ motorbike and Harry now has it.
Umbridge is in jail for crimes against muggleborns.
Rita Skeeter is still alive and reporting mostly rubbish.
Harry would ensure that Snape’s heroism was known.
The Ministry of Magic was de-corrupted, and with Kingsley at the helm the discrimination that was always latent there was eradicated. Harry, Ron, Hermione, Ginny et al would of course play a significant part in the re-building of wizarding society through their future careers.
Did the D.A. keep the coins?
Naturally. They would be like badges or medals of honour - proof that the owner had been at the heart of the fight against Voldemort from the start! I like to imagine Neville showing his to his admiring pupils.
How is the quibbler doing these days?
Pretty well, actually. It has returned to its usual condition of advanced lunacy, and is appreciated for its unintentional humour..
Are house divisions as prevalent in Harry’s children’s Hogwarts as in the previous generations?
Slytherin has become diluted. It is no longer the pureblood bastion it once was. Nevertheless, its dark reputation lingers, hence Albus Potter's fears.
Malfoy’s:
Did Lucius Malfoy, and all the other escaped death eaters, go back to Azkaban?
No, the Malfoys weaseled their way out of trouble (again) due to the fact that they colluded (albeit out of self-interest) with Harry at the end of the battle.
Did Draco and Harry lose their animosity towards each other when Voldemort died?
Not really. There would be a kind of rapprochement, in that Harry knows Draco hated being a Death Eater, and would not have killed Dumbledore; similarly, Draco would feel a grudging gratitude towards Harry for saving his life. Real friendship would be out of the question, though. Too much had happened prior to the final battle.
Is Scorpius as misguided as his father, or has Draco improved and taught his child(ren) better?
Scorpius has a lot going against him, not least that name. However, I think Scorpius would be an improvement on his father, whom misfortune has sobered!
Does the dark mark remain on those that Voldemort has branded after his death or does the tattoo disappear now he is gone?
The Dark Mark would fade to a scar, not dissimilar to the lightning scar on Harry's forehead. Like Harry's, these scars would no longer burn or hurt.
sorry it is really long
