I need to install some new kitchen light lenses. I believe that's
what they are called. These appear to be made of plastic tho I'm not
100% sure. If I need to cut them, what is the best tool for that, a
sheet rock knife or something else? And when I cut it, should the
finish side be facing up or down?

Some hardware stores will cut them down for you. Unless they are the grid
type, get the acrylic ones. They cost more but the styrene ones are more
bittle and turn yellow over time.
