I also found the licensing confusing. You say it's under CC 4.0 but don't specify. When digging deeper it appears you mean CC BY 4.0, but then you link to another page that places specific restrictions on the type of attribution, which CC BY does not do.
What's more, some of these restrictions are onerous, e.g., requiring attribution in an image's text description or requiring a link to your page. Again, that is inconsistent with the license you claim to use, and what's more is you don't have a policy posted on referrer tracking, so for all we know you're essentially requiring telemetry.
In my estimation, you won't get a lot of people using these until you clear up the licensing. While your icons are beautiful (again, great work!) it isn't worth the legal risk.
Oh no, I'll get this fixed asap.
Those 5 icon sets, Bangalore and Freemoji sets are all licensed under the Creative Commons - CC BY 4.0 which lets you use them as you want.
