How many sub domains are covered by Cloudflare Origin Wildcard SSL in the free Plan?

It’s a wildcard. It will cover ANY.example.com, but not SUB.ANY.example.com

So i could cover 1.example.com up to 99999.example.com with one wildcard certificate from Cloudflare?

Yep. But you’ll need individual DNS entries for those.

The wildcard covers one label in the DNS name. A label can be from 1 to 63 bytes long, and contain a-z, 0-9 and -, but cannot start or end with the -. So a lot more than 99,999. There are very few legitimate uses for such a large number of hostnames.

On self service plans you cannot proxy wildcard DNS records.
