Have a 320amp main service mounted on a detached garage. Installing 2 sub panels in main house (120' away) can I run separate conduit runs for both sub panels from 320 amp main electrical service ? Both sub panels will be externally mounted side by side. 200 amp sub and a 100 amp sub.
 
No you cannot have 2 feeders going to the dwelling. Run a parallel feeder and install a trough at the end and tap to the 2 panels.

yes you can. but it almost certainly violates the code.
 
What is a violation here? I see this done all the time, unless I am misunderstanding the question.

If there is no service disco at the meter these are not feeders but rather service conductors and would be compliant. Not sure if the OP is putting service disconnects at the meter though. While the code does not require the service disco(s) to be at the meter location many POCOs do.

If he is putting the service at the garage it would seem likely there is a panel there too.
