ELI5: Why can our eyes look inward, down, and up together but not outwards?

Bonus: Can your eyes get stuck? If so, why?

The eyes are designed so that they both look at the same object.  For very close-up objects they need to converge (look inward) to do this.  For distant objects they're parallel, i.e., looking in the same direction.  There are no circumstances where having the eyes diverge (look outwards) will have them both looking at the same object.

Our brain is only trained to deal with a single image at a time.  Having two eyes is mostly to help with 3D perception and it gives us redundancy (in case one is lost or fails).  It's not so we can look at two things at once.
