let's say I have a origin server 1231.123.12.3123:3000 , 1231.123.12.3123:3001 it has 2 ports open can I use loadblacner to connect to a port ? or it's only connect to ip ?

You can override the destination port with an Origin Rule
this applies for Load Balancers too, I just tested.
this port have be in range of 30000-32767
I want this range for k8s
or only cloudfalre allowed ports
I mean Origin Rules can only send to a single specific port, but Origin Rules do allow you to override to any port yea, doesn't have to be Cloudflare supported. Users wouldn't connect over that port though, they'd connect over one of the supported ones
User -> CF on 443 -> Origin on 30000
free tier has 10 rules does that mean I can only put 10 servers?
no, you'd only need one origin rule to override all origins on that specific lb hostname to a specific port
