- it seems to me, that during POA, there has to be about 10 first
years in each house - certainly less than 20. The canon for that is
that for R&H to miss the sorting ceremony, it would have to be a
really short one, since their calling off by McGonnagall does not seem
like a long one - and don't forget that the ceremony did not start
when they left.

Me:
Scholastic's website has several JKR Q&A sessions online.  

Here's the URL for the following canon:

Q: How many students attend Hogwarts, and how many 
   students per year per house? 
A: There are about a thousand students at Hogwarts.

If we do the math, we get:

1000/4 = 250 
250 /7 = ~35

So, about 35 students per year per house.

Of course, that's assuming that each year, 
roughly the same number of students come
to the school, and that out of that total,
each house gets roughly the same number of 
students.
 
So, apparently, we haven't even met half
of 'em in Harry's year alone.
