Can I connect multiple iPhones / iPads to a singly Macbook Pro and wipe them simultaneously or will I have to conduct each one manually? I have a few hundred to do, so I am looking to this the fastest and easiest way possible.
iPhone 5c, iOS 10.3
Without wifi or cellular connectivity, you're going to need some kind of massive USB hub/cart? Apple configuration is software you run on your Mac to configure devices. There is nothing to install on the devices.

As far as some sort of giant powered USB hub or cart, you'll need to look online for that. There are several companies that make them, although I don't think I've ever seen one that can do more than 3-4 dozen devices simultaneously? I'm also not sure about one device that would accommodate both iPhones and iPads, so you'll need to see about that. Maybe see what companies seem to offer you what you may want and then call and talk to them about your specific needs.
Not with a Mac and just iTunes, no. If that's all you have, you'll have to do them all one by one.
To mass manage devices, you'll need something like Apple configurator or a commercial managed deployment tool (there are many for business deployments from a few to thousands of devices).
Does it require the installation of the app on the iPhones themselves? These devices have already been updated to iPhone 6S units and the phone numbers ported over. They are not active on any cell signal nor can we connec them to an wifi signal.
