The only way you can upgrade a flight on a xONEx, other then the paid per sector premium economy upgrade mentioned in the rules, is subject to the rules of each airline and FF program.

For QF, you can only upgrade with QFF points, on a QF marketed and operated flight.
With your listed QF flights, only QF94 can be upgraded from Business class. The 747's used for QF63 and QF96 don't sell F, and you can't upgrade on the AA code.
