It shows the number of players on the objective. That SHOULD mean how many of your teammates are doing the objective, but there is an exception. Defense objectives are available to both sides. When you're on the attacking team, but you're not the right class for the primary objective, you can take a "defend objective" mission - it's the same "defend objective" mission the entire enemy team will have as their primary.
Oops.
As for the times where the number adds to less than 8, that's easy to explain as well - class-specific side missions don't show on your objective wheel unless you're the right class for them - a Soldier can't see how many Medics are running the "revive friends" mission - and the Medic can't see how many Engineers are running off to build that MG nest.
