with this feat (http://www.d20pfsrd.com/feats/combat-feats/multiweapon-fighting-combat/), yes. Otherwise, you get one off-hand.

It also depends on how you get your extra hands. Many of the extra hands options explicitly say you can't use them for attacks.

Based on the Marilith entry, I'd disagree.

Reread the "Normal" entry for that feat.
Just having 3+arms entitles you to an off hand with each extra arm*. Granted, due to penalties you're going to want that feat anyway.

Also note that there is no "Improved Multi-weapon Fighting" feat. So you never get iteratives with your off hands.


*Assuming your extra arms are useable for extra attacks anyway. Alchemists need not apply.
