Correct. (but see the options about no-cache...)

Correct.

refresh_pattern only decides the amount of time Squid will consider the
object as fresh.. there is no "stale" parameter.
refresh_pattern min precentage max
the max parameter is a upper bound on the percentage based calculation.
If the result of the refres_pattern calculations is less than 60 seconds
and the object cannot be revalidated with the origin server, then Squid
won't cache the object.

Then the percentage of the obejcts age is used but at most 1440
(assuming you meant "max age" not "stale age"). See also the
refresh_pattern options regarding the use of the min age.
> B. Object without LastModified, Expiry header
If the object has neither LastModified or Expires, then the min age is
used.
