Sheriff of Safe Passage & simultaneous creatures entering play
Blinked Sheriff with Another Round. I had four creatures in play. Sheriff only saw itself and the creature I did not blink - they all entered simultaneously, so Sheriff should have seen the other two creatures and gone up to four counters. Instead, it went down to two, counting the one token creature I did not blink.

And that is correct. "[this] enters with ..." indicates an ETB replacement effect, which are applied before anything actually enters. Since the blinked creatures are hanging out in exile together with the Sheriff, the game does not count them.
It's the same reason, why you can't clone a creature entering alongside the Clone.
