Beginner Gardening: Over or under watered tree?, 1 by hage1883

I am responsible for taking care of trees at my office building. I know nothing about gardening so I am kind of just winging it. We have about 6 trees that were just put in a couple months ago. We are in Oklahoma, so the climate is very hot and pretty dry right now. I water the trees every morning except weekends (I water them until water seeps out of the sidewalk cracks, so they are fully soaked). 4 of the trees are doing great, but 2 of them are struggling quite a bit when they were recently thriving the most. I have attached some pictures (sorry, I don't know what kind of trees they are). Could you give me your opinion on whether I am over or under watering them?
