IMO, no standup should have anyone attend that is not a direct member of the one specific team in question. At least, not without really good reason. So, the project manager/Scrum Master for the team, plus the technical members of the team. That's it. You can have guest attendees, if there is a good reason. You can have temporary members, if they're working with the team for a short period of time. But the basic rule should be just the engineers plus their project manager/scrum master. And no one should be in multiple standups without a really good reason. Maybe the PMs or Scrum Masters should be in a Scrum of Scrums, but that's about it.
