Sorry to be the bearer of bad tidings, but your OTA option are essentially limited to the first two channels on your list. XEFA would be easy to receive. KHRR (Tel) would be more difficult but possible. Your next channel has a signal level of -9.8 dB. That's going to be impossible to pull in. If the hill in front of your house is in the direction of Tuscon, you'd probably have to get above it to get a decent signal (assuming there are no other big hills blocking the signals from Tuscon).
