Multiple connections from a single Bluetooth Dongle

I am using a usb bluetooth adapter on my PI 2 , which communicates to an arduino using HC-06 Bluetooth module. This script runs to connect to that module:

#! /usr/bin/python

import serial
from time import sleep

bluetoothSerial = serial.Serial( "/dev/rfcomm1", baudrate=9600 )

count = None
while count == None:
count = int(raw_input( "Please enter the number of times to blink the L$
pass # Ignore any errors that may occur and try again

bluetoothSerial.write( str(count) )
print bluetoothSerial.readline()
And this is what my /etc/bluetooth/rfcomm.conf looks like :

rfcomm1 {
bind yes;
device xx:xx:xx:xx:xx:xx;
channel 1;
comment "Connection to Bluetooth serial module";
Now, I want another arduino and another HC-6 connected to my usb blutooth. Is it possible to do that simultaneously ? I want two and fro data connection from both these HC-06's at the same time.

For more reference, this tutorial is what I followed to get the first bluetooth running :

I don't think this is an Arduino problem. It all depends on whether you can configure the USB dongle in the raspberry pi, and you don't say anything about that. If you can configure that to talk to both of the Arduinos, the Arduinos will have no trouble talking back.
