Rage of Halone debuff is about 7-8% less physical damage taken I believe. Foresight works out close to 6-7% less physical damage taken when it's up (but obviously stacks mutliplicatively with other cooldowns).

Bulwark's mitigation depends entirely on your shield, as the amount of physical damage it reduces varies depending on Kite/Tower/Buckler type. Kite Shields are around 20-21% mitigated per blocked hit, Tower Shields more like 28-29%, so it's that amount with +60% chance to block on top of your actual block rate. You can generally count on -most- hits being blocked here, so in most cases Bulwark means you'll take about 20% less damage whilst it's up (from physical attacks from the front). It's not 100% reliable though so is better used for packs or multiple hits (like Holy Bladedance in Thordan Ex).

Crits in FF are +50% damage, and I think most mobs average about 5% crit chance, so Awareness is only going to be around 2-3% less physical damage taken. However, if a mob crits that crit cannot be parried or blocked, so Awareness sort of increases your parry/block rate a little when active. In general this is by far your weakest cooldown, the advantage isnt so much in the amount it mitigates, but more that when it's up you wont ever get an unexpected burst of damage from a huge autoattack crit that might catch healers off guard.
