Joining with the server http://vault.centos.org there is a redirect to https, to the server https://vault.centos.org it offers only modern encryption algorithms, so yum on CentOS 5 will not be able to connect to this server. You should change http://vault.centos.org on http://archive .kernel.org/centos-vault. Here is a more detailed description of the problem https://stackoverflow.com/questions/73047179/yum-update-return-ssl-error-on-centos-5-8 .
