Hello! So I'm currently working on an animation, using a model I recieved from Models Resource. I was lucky enough for this model to already come with its own rig, and its been working very well for me so far. I do notice however in the Nep files, there are other faces that can be used. I'd like to try using the faces so my character doesnt have a blank expression on their face. If you know how this is done, please share!

What software are you using to animate? I'm aware of how it should work in MMD and Blender
For MMD, you need to create a UV morph that will allow you to offset the texture coordinates. I often don't bother trying to do this in pmx-editor and instead use Blender + mmd tools. It's a bit complicated so if you'd like I can make a video of me doing it, but then once the morph is completed you can just use the slider to change it.
For Blender (2.8+), you want to use the Shader Editor and then use mix nodes to swap between UV Maps for each face. What I like to do is use a driver to animate it, but you can also just animate the mix node itself. As you can tell from this explanation this is also kind of complex so I can demo this also.
