Different volumes means different bricks/disks, right?
Yes
So, if I would like to have all replicated 3 times (1 disk per server)
with 2 volumes, i have to put at least 2 disks per server?
Ideally yes.

Any differences between replica2 + arbiter or replica3 without arbiter?
Replica 3 should be more safe, as data are replicated 3 times.
Replica 3 is more costly compared to Arbiter. If you are comfortable with replica-3 that is the best option.
