I know that there're three component which is console, proccessor and collector. I will deploy console and proccessor at HQ and collector at branches for receiving log. All component is virtual appliance.

My question is 
Is there any cost for collector at branch?
Where's location for install license? Is it Console?
Do you have a number of EPS limit on each components?

If the Event Collector is going to be installed on a virtual machine or own server, then there is IBM QRadar Software Node Install License that applies per instance of installed QRadar image (it is basically there to cover support for (re)used OS software code).
There is a free option, though, that might be acceptable - DLC (Disconnected Log Collector); have a look at IBM Knowledge Center - DLC
Licensing is always deployed and allocated using your console instance. Collectors do not have EPS/FPM license applied (this is reserved for Processor instances), but should be sized accordingly - e.g. have a look at QRadar memory requirements
