Thanks for all the advice. We did enjoy the lounges on our last RTW. JL Sakura was very nice, we spent a bit of time in the massage chairs. Any other lounges feature those? In HKG, Cathy Pacific's Pier Business Lounge was good for a shower (shower room is full restroom) and nap.
In DOH, visited Al Mourjan for shower which had quite a line and has seperate restrooms a distance away. Line for the waiter service food.
All three very nice to visit between flights.
So now I need advice for ICN, MNL, KUL and OSL again

Also will go thru DOH twice, one short visit and one 5 hour visit. ICN has the oneworld lounge, does it get croweded? Will be leaving MNL on Malaysia Air so Marhaba would be an option but they have a JL and CP lounge as well?? Then KUL has the Malaysia Air and a Qatar lounge?
Regarding OSL, we will arrive on a business class QR ticket but depart on a AA econ award ticket two hours later. Would we have OSL Lounge access? Not sure it really matters for such a short visit but the QR might be a bit early allowing more time.
Again thanks for the help.
