20 ghosts

In SS p. 115 it says: "About twenty ghosts had just streamed 
through the back wall." 

Now, my question is, is it important for us to know who the other 
ghosts that we don't know yet are?

In that scene they are talking about Peeves not being a proper 
ghost, therefore, we can assume that he is not amongst them 
(apart from the fact that he is a poltergeist who perhaps can't go 
through walls like ghosts, as he can throw around things and the 
fact that Harry probably wouldn't be able to discern between a 
ghost and a poltergeist at first)

One of those ghosts is the Fat Friar (p. 116), we are later 
introduced to Nearly Headless Nick and the Bloody Baron and the 
Grey Lady. Although Harry doesn't mention it, I'd think that Binns 
was at the Head Table and not among the group but of course, I 
could be wrong. That makes 4-5 of the twenty so far.

In book 2 we are introduced to Moaning Myrtle but she seldom 
leaves her toilet (except to spy on the guys in the Prefect's 
bathroom), so I doubt she's be among them.
Even if she had been that means we're only up to 5-6.

If we meat any other ghosts in the book, I can't remember but it 
can't be more than one or two. That leaves 12-15 ghosts floating 
around Hogwarts that we haven't heard anything about yet. Are 
they staying out of the students' way? Or where they just never 
mentioned because they weren't important for the plot? Or 
wheren't they mentioned because they will be important for the 
future plot but would have given too many hints if they had already 
been discussed? If they have no relevance for the plot, why where 
they mentioned at the beginning of SS?

Any thoughts?
