I believe technically you could, but I don't see the point - these are vms so just make smaller instances. Do you have a limitation on the number of vms you can run?
If you do want to go ahead with it I guess just unzip the tar into different directories and give them different management ports when you start them up. You'll also need to configure different ports for all the inputs. And you'll need to change the web server port as well.
In fact you'll probably need to change every 4 digit number in all the configs, as the limits.conf will probably be breached depending on how much disk space you're going to devote to the vm
