Nicholas Alkemade, Alan Magee, and Ivan Chisov all left their airplanes at 20,000 feet (ish). All three took significantly less than 30 minutes to hit the ground (closer to 2 minutes, I think), and all three lost consciousness on the way down.
I’m not sure if their planes were pressurized, what oxygen they may have had on-board, or how long they had been at 20,000 feet before their bombers were destroyed.
None of the planes were pressurised, very few were in WW2, they were all breathing from some kind of oxygen source and bombers would typically spend 3 to 4 hours at that altitude on route to their targets.

In 1966, an SR-71 flying at 79,000 feet and Mach 3 disintegrated in mid air. Pilot Bill Weaver survived with few injuries: https://www.youtube.com/watch?v=mnEgS3buPb8
As already mentioned, Juliane Koepcke survived free falling from 10,000 ft when the Lockheed Electra she was in broke up in mid air.
Juliane Margaret Beate Koepcke /Joo-lia-nay, KOP-kay/ (born 10 October 1954), also known by her married name Juliane Diller, is a German-Peruvian mammalogist who specialises in bats. The daughter of German zoologists Maria and Hans-Wilhelm Koepcke, she became famous at the age of 17 as the sole survivor of the 1971 LANSA Flight 508 plane crash; after falling 3,000 m (10,000 ft) while strapped to her seat and suffering numerous injuries, she survived 11 days alone in the Peruvian Amazon rainfor...
There are many sole survivors of aircraft accidents. You’d have to research how many happened at high altitude: List of sole survivors of aviation accidents and incidents - Wikipedia
