Tree number two looks like an ash of some kind. You can search for trees (and other plants) online at the link below. All the choices would be appropriate for our location in the low desert. Just click on the 'plants' tab and select by common or botanical name and choose the characteristics you want. Good luck. Here is a link that might be useful: Water Wise Plants

Don't plant anything hear the pool with small parts that will get into the filtering system

nope.. no experience with the foo foo RBs ... they are problematic in my z5 MI ... you see one once in a while.. but they dont flourish ... the only problem that i had with crabs.. was their proclivity to send up suckers at the base after a bout 10 years ... you would have to try to find ones that dont do that .. or move in about 7 years.. lol ... dont get confused and compare to red leafed plums ... just dont.. stay away from those .. black knot .. ken

@Dig Doug's Designs Thanks for the suggestion. I really like this tree but there are several in our neighborhood and they seem to make a mess with leaves dropping all year round. With it's proximity to the pool I worry about the leaves blowing in constantly. @Embothrium I realize that the pictures might be a little confusing. The 2 areas I am looking for help with are the 40' gap on the side of my property (behind pool eqip pad) and the area in front of the telephone pole. I don't need to cover the pole entirely but i don't want it to be so visible. My original plan was to plant a Dakota Pinnacle Birch in front of the pole with some smaller shrubs below. Then I was going to plant a line of evergreens (not sure what) in the 40' gap left by the trees that fell over. My wife would prefer something flowering somewhere (preferably in front of the pole). I'm not opposed to it but I don't want anything with a large canopy that would force me to push the tree further away from the pole and into the yard. I could do some flowering trees in the 40' empty space but I thought it might like disjointed from the existing line of evergreens along the side. In reference to the Emerald Green Arbs I was planning to use.. they would be about 8 ft away from that fence I am trying to screen. Also, my front door faces south so the sun is over the house providing full sun to the yard for most of the day (about 10am to 4pm). The pics below should provide a better picture of what I am talking about. Please excuse my 1st grade art skills.
