Ximkee(10 Pack) Large Rainbow Badge Sequin Sew Iron On Embroidered Patches Appliques

What size is the largest rainbow iron on?

If I’m using a heat press what temp and seconds should I use

are all 10 patches the rainbows or are there various designs in the pack?

7 patches are pictured, but the description says it comes with 10. What are the 3 remaining patches of? Are there more than 2 rainbows?
