Edit /etc/yum.conf and decrease (or increase) the value of installonly_limit. The default is three which causes yum to hang on to the two most recent old kernels. Those two plus the current kernel are the three that installonly_limit means.

After checking /etc/yum.conf, then find out if all of those really are installed...
rpm -qa | grep kernel | sort
If you're willing, post that. Also post the grub.conf file. It might be interesting.
