Most of them are locked behind main scenario quest completion, the ones marked ??? will be ones you've not got to get. There's also a few quest givers in Mor Dhona that unlock dungeons, so make sure you've grabbed everything available there as well.

You need to unlock and complete all level 50 4-man dungeons excluding those added by patch 2.5. If they're listed as ???, it means you haven't even found the dungeon yet, nevermind completed it.

No they're not. 2/3 of them are simply go to X and talk to X.

No they're not. 2/3 of them are simply go to X and talk to X.

Go to X and talk to X after having completed the 2.0 Main Scenario. They don't require the 2.1 - 2.55 updates to the Main Scenario, but nearly all require having finished The Ultimate Weapon.
