How does one go about making a second or even third character? Can I use my same Minecraft account and just do another application? Is there a way to switch personas on the same in-game account?
If you do /menu ingame, you can create a new persona. I believe you start out with 2 slots and can get more by boosting the server and buying VIP. You don't need to do another application or use another account, that's just for when you first join the server
