It seems to me that the four acrylic templates included in the drop are specifically for the Can Can quilt. The others to the left are templates that can also be used for other designs and can be purchased separately if you do not have them already from previous designs. Some are familiar to me and I may already have them, such as the J and K templates that were included in at least two other designs for which I bought the templates, I will just have to double-check my supply. All in all, by having started other English paper pieced quilts ,I can say that the paper pieces are more important than the acrylic templates. The acrylic templates allow you to fussy cut the fabric more accurately each piece, that's all. For some blocks, I remember cutting the fabric around the paper piece, leaving some allowance for glueing edges but not necessarily being very precise on the amount of fabric left. You can still fussy cut without using the acrylic templates, they just make it a bit easier.
