I wouldn't do the second and the last one is a bit busy, the other ones are great.
Depending on the size of quilt that you would like, and the size of repeat, you are looking to have multiples of 6 of the repeats,
if it has a 24" repeat (2 feet) for 6 repeats you need 12 feet equals 4 yards, so if you need more you are looking to buy the fabric in multiples of that, so the next break would be 8 yards, of course with the different sizes of the repeats and what you are doing will depend on how much you will actually need.
