You have more than enough for 5 days of shooting. I spent 5 days in Death Valley alone and it wasn't enough time. I'd shorten rather than lengthen the list. It's going to be very hot in some of those locations. Drink/take plenty of water. Some alternate locations very near Las Vegas include Red Rock Canyon and Valley of Fire but your plate is already too full.
