The butterflies & the solid definitely match. I think the 4th fabric with the hot pink & olive green is so different you'd have to add more fabrics to get it to work with the other 3. It is substantially more saturated & the green is more of a yellow-green (olive) versus the blue-green that's in the other fabrics. You could potentially make them work by adding in the direct complement of olive (periwinkle) in a fairly saturated hue. Otherwise, I'd probably stick with the first three and then work in some blues or purples to add interest and vibrancy; or else go with a muted palette and add in some greys or beiges and more shade of pink.
