Quilt #1 appears to be the easiest to me. As the others have said, you just need to pick you colors and cut the strips to the width of the bed. You will have to change the measurements given in the pattern but that shouldn't be so hard.
If you have trouble with it, try this. Keep taping freezer paper together until it is the size you want the quilt to be. Draw lines on it to represent the different colors you want to use. You can then use this pattern you have just drawn to measure how big each strip needs to be. Be sure to add for the seam allowance.
