Warbler Identification Questions

This morning I heard unusual bird calls outside the window, followed by a great deal of activity and flitting about in my large maple tree. The streaks of yellow signaled me to grab my camera and head outside. I was able to capture three different species of warbler (I think) and would appreciate some help with the identification. I believe my main blip is a Magnolia, one of the extras is a Northern Parula, and the third I can't figure out. Did I get them right, and what do you think about the third? Thanks for your help!
