Yes. Assuming this is 2.7 (where collapsed forwarding works) one client
will be downloading and others waiting for the same URL will be sharing
the trickle as it arrives.

If these are publicly accessible URL you can plug one of them into
redbot.org. It will tell you if there are any caching problems that will
hinder Squid.

Otherwise you will have to locate and figure out the headers (both
request and reply) manually.

Not being able to cache these objects could be part of the below problem...

Check what that is. You can expect all clients to parallel download many
objects. But they should still be bandwidth limited by Squid within the
delay pool limits.
