Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

We currently run 4 onsite web servers and 1 offsite server. Four of our severs run Apache 2.x webservers, while the one other server runs Tomcat.

The server which runs on Tomcat contains third party software, and we can't change it to Apache.

We have one domain name, and several subdomains pointing to each of the servers. For instance:

sd1.domain.com - Apache Server - Windows
sd2.domain.com - Apache Server - Windows
sd3.domain.com - Tomcat Server - Windows
sd4.domain.com - Apache Server - Linux

As you can see (in my crude example), although the server software changes, the domain name still points to the servers.

My question is, we are looking into purchasing a wildcard/multi-server SSL certificate. Will I only need to purchase one certificate for all servers, two certificates for windows/apache or three certificates for apache/tomcat?

A single wildcard certificate for *.domain.com will suffice. Certificates don't care what kind of server is being used.
