For one thing, zppy.lupoinfo.com.br is not online. You may want to remove that repo.
The other 2 repositories are working just fine, although there are currently no modules available at store.sentora.org/repo (Can be removed also)
zppy-repo.mach-hosting.com/repo/ is working just fine.
I am not sure why it is showing you an error for it.
I am not sure why you can not connect especially if your firewall is down.
Check your server's host file just in case there are entries for the repositories pointing somewhere else.
