Does a single interface support multiple service-policy’s commands?
Yes, two; an in and out policy.
Should I configure the new class-maps’s that I’m going to define into the same policy-map I already have defined?
Yes, you might. You might also define multiple match statements within the same class-map. Or, if a match statement is invoking an ACL, that ACL could have multiple statements. It all depends on what you're match requirements are.
Remember within the policy map, class maps are processed sequentially until a class is matched. Within a class map, match statements are also processed sequentially, but whether the process stops on an individual match statement depends on whether the class-map is using match-any or match-all.
Also keep in mind, depending on your platform, class map match statements might allow NBAR matching which can examine packets beyond just port numbers. For example, TCP port 80 is normally used by HTTP, but the port might be used for something else or HTTP might use a different port number. "Match protocol http", I believe, should look for HTTP statements within the packet, i.e. it should match (or not) regardless of the port being used.
