1.) Sorry, can't help you with that. I never used cloudflare for DNS before, so I don't know how to set that up or if there is a problem.
2.) Where, in cloudflare? Anyway I don't use cloudflare, so I don't know.
3.) IntoDNS says that's good, but if I do a nslookup on ns1.hostcardano.com it does not give me the correct ip, could be caused because DA is not responding on port 53 requests.
4.) Might be good, can't say from here. If it's like in your first screenshot then it's good.
Did you open the necessary ports in your firewall?
Maybe it's due to some error in the /etc/named.conf that might also be possible. Because it seems ns1 is still not responding.
Can you give the output of this command:
lsof -i:53
		
		
	 
I waited 3 days to see if the dns could propagate, but nothing, it still does not work
I have removed the cloudflare and now I am pointing the nameservers directly to my server ip
the firewall is open

still not working, I waitted a few days to see if it was the dns replication but nothing
now I am not using cloudflare anymore, I pointed the ns directly to the server ip
port 53 seems to be open when I try a port scanner and the result of the command you ask is this
