The one on the very top with no number appears to be a sunkissed. Then number 1 is an amel, number 2 is probably an ultramel (possibly a different hypo type, but ultramel would be my best guess), number 3 is a stripe, and number 4 is a cubed stripe.
Cubed is just the presentation of the stripe. It’s still genetically a stripe, but instead of the normal stripe presentation, which is two narrow stripes running the length of the body and breaking up into little dashes, a cubed stripe has little bowtie or cube shapes. Again, still ‘just’ a stripe genetically speaking, but looks a little different than what stripes normally look like.
