I wouldn't worry about a pattern, but pick one or two other fabrics that compliment all these to use as sashing and borders, then just put these in scattered thru-out the top for a scrappy looking quilt. Looks like the beige floral at the top is the only one not directly related to the others, but I'm guessing that there are colors in it that will coordinate, so another beige floral might work if the right colors are in it...or a beige/black/green/purple combo of some kind. In essence you're making new fabric.
You could also pick ones you like and put them together for a quilted sweatshirt...
