I see these updates in Software Updates (released May 11, 2016) but my MacBook Pro can not update (see 3 second and disappear), my Mac mini can install update.
I updated them last night. However, I noticed that it took a very long time to download and do the updates. I suspect the Apple servers were having problems. The iOS versions of Pages, Numbers, and Keynote downloaded very fast compared to the OS X versions. Probably downloaded from a different server.
