CallManager Public Signed Cert 10.5.2

!Im adding a subcriber into the cucm mixed mode cluster (ver 10.5.2). I have checked how the certificates for the other call manager servers in cluster were configured from the public CA(digicert). Apparently there was an individual CallManager certificate for each servers.

Is this the right way of doing it ? Do I need to buy and issue a new certificate for the new subscriber call manager ?

Mixed mode clusters do not require public/private CA signed certs on CUCM, it is optional.  I would suggest checking to see which certificate type (CallManager, Tomcat, etc.) is signed by digicert and following the same approach for the new subscriber.  CA signed Tomcat certs are the most impactful as they are used for https sessions in browsers, jabber, and more.
