Sorry I missed replying to this comment, The ones you shouldn't use for commercial use are the ones listed as free on our dafont page (this link should show you 23 fonts in total): https://www.dafont.com/chequered-ink.d6231?l[]=10&l[]=1
except CI Game Dev and Teeny Tiny Pixls are allowed. They're just usually free.
And not all of those fonts are in the pack anyway because we left out some of them on purpose to avoid any issues.... but just in case any of them snuck in those are the ones to watch out for.
