How you use that ACL in your access rule logics is just as important as
what it contains / matches.

The pattern is malformed. Several parts of it are impossible to match,
and just make it look complicated when its not.
It is better written as:
^http:\/\/igcdn-[a-z0-9\-\.]+\.akamaihd\.net/hphotos-ak-[a-z0-9]+/(t5.*)
http://instagramcdn.squid.internal/$2

Store-ID does not force caching. All it does is provide Squid with a
different ID under which the item would be stored *IF* (and only if) it
would be stored normally.
I suggest removing the "ignore-no-store ignore-private" from your
.squid.internal refresh_pattern. They trigger actions that break the
image objects you actually want to store at that Store-ID location.
