1. and 2. I am rather worried why no one has answered this yet after 8 hours. Leaflets in 3's let it be. Surely this is Poison Ivy,Toxicodendron radicans, there is also another vine in pic1, which looks like a honeysuckle. Please see this link. http://grandpacliff.com/Plants/PoisonIvy.htm
Agree first one is a legume. Looks sort of like Strophostyles helvola. You will know when it blooms. And there is a honeysuckle.
