Marseilles 17 kill day was never confirmed properly. But is rather established that he hit 17 aircraft that day.
To get 10 confirmed kills in 15 minutes, you need many eyes to either confirm disintergration, a bale-out or a ground smash.
Getting to McCambell, how many kills did he get in a day? like 6 or so?
Robert Stanford Tuck got 5 kills in a day over Dieppe, where (due to smoke and haze) it was difficult to find the enemy. He got shot down eventually, later on, by a flak unit. He actually did put a bulled through the flak gun´s nozzle!
That is something.
And then it was "Screwball" Beurling. IMHO the best shot of the war. Must have had eyes of an eagle. Shooting up planes with wing guns rather than the central mountings, and both aiming for the vital parts as well as counting the strikes who later got verified is absolutely unique.
Malan made a mess of Mölders, in an epic dogfight. Malan engaged and shot down one of Mölders men. Mölders made no mistake and with his plan came down on Malan's six. Malan easily outmaneuvered Mölders and peppered him into a cheese filter before letting go, and there were 2 possible reasons for that, - one being the need to break away, and the second (famous for Malan) was to spare his enemy so he could go home wounded and humiliated. He did that actually on several occations.
Rall, - a crack shot and excellent flyer, and if he had not been injured during a vital phase of the war in the east (like a year or so), he might have topped Hartmann. On the Western front he was injured again, and he stated it had saved his life, for closing on enemy figher formations like the high flying P51's and P47's and being outnumbered, was close to suicide. He got shot down by Zemke's pack (P47), and with a grin he said that probably saved his life. He did get shot down some 8 times, and one noteable German Ace 17 times.
Then the coolest. "Pat" Pattle was the top scoring RAF ace with some 50 victories, there off some 15 in a biplane! Top that!
And that was just the pilot part, . . sigh
