4 attacks + action surge
This will net you two attacks per round [main hand] + 1 attack off hand [bonus action] + plus action surge.

Yes, but you only get one sneak attack per round.

Level 3 thief grants a second bonus action, which can be used to off hand attack.

So two main hand and two off hand (all with proficiency).

Then there is also riposte attacks.
