I had XAMPP for Mac installed - working fine for a year or more. Suddenly, I would try to view localhost sites and got nothing. No errors, just a totally blank page (view source shows nada). I uninstalled and reinstalled XAMPP - now I try to start Apache and get an error that something else is running on Port 80. I found a suggestion to run

sudo lsof -i :80 # checks port 80

on the Terminal so I did that and got the info below. I have no idea what any of it means or how to stop all of this stuff so I can start Apache. Any help will be MOST appreciated.
