It should be about 6-8 entries when it's finished.
How do you know your parents are also being selected for security screening? Are they also applicants or they just check them because you mentioned them in 'family' section?
I've heard there were cases CIC missed response from CSIS. And after getting their reply and raising CSE with it's scan people were getting PPRs shortly.
Sometimes PPR comes the same day.
Sometimes you have to wait for a week or two.
And sometimes they select you for security screening and you wait 9 months-2 years
