You are the only one who can answer any of those questions. What you
count depends entirely on whether counting each particular piece of info
is useful to you.

Wireshark will give you exact count for whatever you choose to measure.
Neither of the above measurements is relevant to Squid.

If it's just HTTP request/reply data flowing through Squid that you are
interested in the Squid access.log will give you exact byte counters of
header+object size with the %st logformat tag.
