Can someone explain the ToO consumables? (Destiny)

I get what each one does individually, but what I'm wondering is how it works across a team. Does each member have to use the consumable for it to work? Take this scenario for example: a team hits three losses, which should mean their Trials run is over, but one member of the team uses the consumable to get the loss forgiven. Does the whole team get to keep playing until they get another loss? Or are they done?

Also, do you have to use the consumables before the games start, or can you use them anytime during?
