Yes - data is still being written out. 'wa' stands for waiting for io. As
long as 'us' and 'sy' are not 100 (together), your system ('computing
power') is not 'busy'.
The lines below are perfect:

Wether you should have 5 pdflushes running is something I have no relevant
experience about, but your system should function just fine during writeout.
