Courageous Resolve doesn't prevent damage. Rather, it changes the results of that damage. For example, if a creature with lifelink deals damage to you, you won't lose any life, but its controller will still gain that much life. Similarly, if a creature with infect deals damage to you, you'll still receive that many poison counters.
Courageous Resolve
Spells and abilities that would normally cause you to lose life still resolve, but the life-loss part simply has no effect.
Protection from your opponents means that the target creature has protection from each object controlled by those opponents. If an object has no controller (such as a card in a graveyard), its owner is considered its controller for this purpose.
