You can MAYBE buy one during an event, but you usually have to buy it from the Nx Shop. ( I really doubt that you can buy one in an event, because I've been playing for more then 3 years, and only sometimes i see cool event masks.)
you find It in Excavation Sites 1-3.
From the road to Perion to Ellina.
Gach.
YES!
its VALEFOR and you have to kill it in the dark portal before you are level 40
Only thieves can receive the Valefor hat. You obtain it after completing the quest, 'Catch Valefor!'
Those were available for a Mardi Gras event, I'm not sure if they will be available every year.
That is the Andras Hat. If you're an Aran, Dawn Warrior or Warrior you can get it by doing the chain of quests that probably start with Dances With Balrog.
