Who participates? Players. By definition, all 6 on the court are players in all these situations, are they not?

Nope, players are legally on the court, so you can never have more than five players from either team at any one time. You can have six team members participating.

BTW this happened in a Big East game about four years ago involving Georgetown. The opponent had six take the floor following a time-out with under 10 seconds remaining for an inbounds play. They scored a basket, then Georgetown beat the six-man press to score at the other end and force OT. Mike Kitts was the R and he owned up to it and told the conference to penalize him, but all three officials were suspended.
