You don't have a check_yum in your libexec output, so that's probably why the check_yum isn't working.
Did you run chown -r nagios.nagios /usr/local/nagios/libexec on the remote host as I suggested you do before? Was there any improvement? I'd expect you to still have some problems, but that might clear up some.
Please run service xinetd restart and then run ps -aef | grep nrpe again.

I was doing some testing and was having issues. I reinstalled the agent (without removing anything first) and that resolved my issues:
https://assets.nagios.com/downloads/nag ... _Agent.pdf . Make sure you do this on the remote host.
There is a large caveat that you will need to back up any custom commands in your nrpe. It doesn't look like OP has any, but leaving that caveat for anyone else that might find this thread later.
Once you've installed the new agent, please resend the common.cfg, nrpe.cfg, and /etc/xinetd.d/nrpe so we can verify the install went through correctly.
The install should restart xinetd, but in case there is no change, run
service xinetd restart. If that does not resolve the issue, run
grep nrpe /var/log/messages. If there's still nothing showing up there, you may need to speak with your Linux admin about where your system messages are stored.

just looking at the lsof command I don't why it is IPv6 instead of 4

On the remote host, what's the output of find / -name npre and find / -name nagios?
