Yup, you can request sub-sub-domains for existing subdomains (assuming you were the person that requested the subdomain, or the person that requested it gives you permission). One thing to note though is that sub-sub-domains cannot go through Cloudflare's proxy, so all sub-sub-domain entries in cnames_active.js will require the // noCF comment.

btw am i also allowed to use this domain for something like vercel hosting instead of github pages?

Yup, any host that you can CNAME to will work :)

It depends what host you're using, they will likely have docs on using custom domains
