For the Hong Kong one, I'm quite sure they're refuge floors. They're left empty so in case there is a fire people can evacuate to these areas.

For WTC NY, you need to watch Discovery Channel. One episode, they explain the whole story of WTC, from the rise to fall. The building was so huge, so to build it, they had to divide into 3 parts. Also for the elevator. They divide the path of elevator, instead of making it from ground level to the top directly, they divide to 3 sections. This is good for workers and more comfortable to handle the crowd.

I don't think it's possible build a single elevator all the way to the top of the WTC. Existing technologies don't allow that, so skylobbies have to be built so separate elevator shafts can rise along the whole height of the building.

I think they are mechanical floors that have HVAC, electrical transformers and water equipment. Probably the elevator motors as well, id imagine the skylobby is the floor below the "bar".
