Nope, not within HTTP. The responses is sent in the order the requests
was received.

To interleave the messages a new protocol needs to be designed, but I
don't really see the much difference from sending the requests on
different connections..

multimedia streaming over HTTP is not something to encourage. It's
definitely the wrong way of doing streaming.

??? Group by which means? HTTP does not define any "groups" of requests.
Just sequence.

Squid automatically merges concurrent requests for the same cacheable
response as soon as Squid knows the response is cachable.

If you enable collapsed forwarding then Squid optimistically assumes the
response will be cacheable and delays the next requests while waiting
for the response headers.
