I visit Taipei zoo today.The zoo opening hours has extended in summer Saturday, so I can see some more things.Good things is the pangolin and the ferret badger is active,and the BoP and serow and crab eating mongoose and a lot more is viewable. I will have a review and a species list when I'm back home.
Those five species you mentioned are going to make this a superb visit if you get to see them. The only other one that I would make a priority is the Formosan black bear.
