I believe that this first image is a photo of red columbine, also sometimes called wild columbine. It is a perennial that is native to Wisconsin and Minnesota. It can usually be found in rocky woods and blooms in the spring.
This second flower was a little bit more difficult to identify. I believe that it is some form of Iris Virginica. From looking around on the Internet it appears that there are different forms of the Iris Virginica, most of which look alike, depending on what part of the country that you find it. It is most likely the L.Var.Shrevei(small)E.S. Anderson variety which is pretty common through out most of Wisconsin according to the Robert W. Freckmann Herbarium, which publishes the book Wildflowers of Wisconsin and the Upper Midwest. This flower is sometimes also referred to as the blue flag, Shreve's Iris, or the Virginia Iris.
