Tascam Driver

I'm deciding on wich interface to buy, and I narrowed my choices down to the Tascam US-16x08, atleast, I think so.
So I have a question about the line outs on it:
I had the idea that when I have a band jamming on that they would each plug a set of headphones into these line outputs so that they can hear themselves play, and a click track or drum beat.
I did some tests in my DAW, FL studio 11, and I found a way to route this, but I came across outputs that were paired.
I mean it wasn't 2 mono outputs but 1 output that would say something like 'audio driver output 1-2'.
So I know the Tascam has 8 outputs, but are those paired as well? So basically I would want to give each member of the band a separate signal, and we're talking about a band of 5 persons here, So if all those line outputs were mono but paired, that would mean I could only send a separate signal to output 1-2, 3-4, 5-6 and 7-8, so 4 actual separate signals.
I just need to know if I can have 4 or 8 separate signals.
Thanks in advance,
