I know this because I've just finished compiling previews of them all into a PDF which I have posted in my Facebook group Cricut Explore, Maker and More.
Head over there to download it. (Click the link above.) You'll find it in our Files section. It's totally free!
I'm also putting the finishing touches to my "Complete guide to Cricut Fonts" book. It now includes previews of every Cricut font (that I know of) as well an expanded section on how to use fonts in Design Space. (Cricut and System.)
I'll post when it's ready. The current version is available in the sidebar of this blog. It's only current up to last year though.
