1. "TWO INTERCONTINENTAL DEPARTURES AND TWO INTERCONTINENTAL ARRIVALS ARE PERMITTED IN ASIA. ONE OF THE INTERCONTINENTAL ARRIVALS/DEPARTURES MUST BE A TRANSFER WITHOUT STOPOVER BETWEEN THE SOUTHWEST PACIFIC AND EUROPE" Therefore, you can't do Pacific-x/Asia-Africa

3. This you need to check with the airlines. If Pacific-Africa is not considered backtracking, then okay, if considered backtracking, then no.

4. Same as 3. If Africa-Pacific is not considered backtracking, then okay, if considered backtracking, then no.

5. You can't do Africa-ex/Asia-Pacific.
