We have helped several other schools is your position this year.

The best option appears to be setting up a proxy on one machine which
provides a gateway for all the others to use.
That way you can secure all the Internet traffic through it and convince
the provider to let just that machine have access out.

If they have a gateway of login system as you seem to indicate (one
account for your school) then your gateway proxy can be setup to do the
login outwards and students/teachers only connect to squid for access
through it.

Tricky, an no guarantee that it going to work any better.

No. The cache is a semi-independant fs that reside partially in memory.
There is no way to do that safely.

I think you misunderstand what squid does.
It provides a nice way for many people to use the same files from the
internet and less bandwidth while browsing.

Best bet taking the route you propose would be to setup an internal web
server outside of squid and put the file into it a website for the teachers.
