Q.Potted Colocasia Elephant ear plats.
I have them in a shade / sun area. Water them regularly, but they are drying up. They have brown around the edges. As for the dead ones. Can I cut them from the plant?

When you water, do you add enough water so that it drains out the bottom every time you water? Elephant ears like moist to wet soil and will grow in several inches of standing water. Depending on the size of your container and your growing medium, it may need lots of water daily. Certainly being too wet is preferable to too dry. Older leaves die off naturally and can be removed. They are also "heavy feeders" and need a regular fertilization.
