Can we safely remove two of these, or would it break stuff if we remove them?
Yes you could, by depending on the situation, you might have to account for the following complications:
Jquery has had some breaking changes with its updates over the years, so an app might be depending on an old version of jquery, or newer one. so you'll just have to double check the one version you load works for every app and your store
You'll have to make sure that your version of Jquery loads before any of the apps
3. It might not be possible
Sometimes an app will call some code, and INSIDE of that code, they call Jquery, so there's not really much that can be done there.
