4.Can you miss with special attacks ? Can they crit ? By special attacks I mean retaliate, shield bash and counterattack.
4) Unfortunately I cannot answer this one. Since I prefer passive bonuses and buff skills, neither me nor my mercs have any aggresive special attacks.
4. After some test i never missed a special attack. But the special attacks was mystic spells (Sickness & weakness). Also i tried ranger's flame arrow. If by special attack you mean for example shield bash then i am not sure but since have chance... I guess that if you manage to perform it then it will not miss. But if you consider taunt as special attack then yes have chance to miss, after all it is clear-> higher level less chance to resisted.
2. I have two mercs with taunt. They use taunt at every enemy (in enemy's turn) who have choose to attack other member of your party. When they are dead or out of spirit or they have failed using this skill at an enemy then they are not using again...

Vicious Robber has been defeated!
As we see here they stop using taunt skill when they failed to taunt the enemy...(Block is performed by Crassus)
And they stop using taunt skill when it has been successful to an enemy.
It is like mystic's weakness & sickness they are performed one's to every enemy have select other team member to attack.
ps. I have not answered those 2 questions coz i wanted to test them before...
