You can create multiple virtual machines. I know that will consume a lot of space on your hard drive, but isn't that one of the purposes on running a Virtual Machine?
Yes, you can copy virtual machines. I made an install of Win7 in a "clean" state, then I "reclaim disk space", then zip it...This way I always have a "clean" windows 7 to start with. (previously with winXP, and now with Win8.
For your purposes, you can easily make copies. Just make your initial installation, shutdown the virtual machine. Navigate to the VM in the finder, click on it, press CMD-D (or Apple-D if you are cool enough to still have the apple key). I recommend that you RT-Click on the new copy that appears, select RENAME, and name it something descriptive. Double click on the new copy, when prompted click COPIED, (Choices are COPIED or MOVED).
Do this for each type of IE you want to install.
