another noob here so no professional help just my opinions. I think maybe a different time of the day would have been great for this shot, it looks as though the sun was just in the wrong position and there was too much reflection given.
Also whenever you are doing portrait shots in the sun, be sure to keep a hanky on hand as many guys will get sweaty faces giving a shine so a quick dry off before each shot can help here.
I like number 3 simply because it was not your idea, dont take that the wrong way but if that is the way they are then they will love the photo even more and it makes your job easier, shows a bit of their personality in the photo.
overall #2 is my fave, they look relaxed and there is not a great deal of overexposure. the sky has character as well.
