You are not the first person to show up here with pictures of an aloe wilting in the AZ sun (and probably won't be the last). I should have added that it might be helpful for you to contact the seller and get tips from them about establishing your new plants in the garden. Local advice is often the best. I would say it's borderline negligent to sell these plants to a newbie in your climate without offering some basic advice about exposure and water. Or maybe it's just a way to ensure the customer returns to seek a replacement plant. I dunno. The first year is the hardest, it gets dramatically easier after that, and I have seen Hercules plants grow to the size of a house in your climate, so there is immense potential there.
