About the license to jira

Whether the license can launch multiple instances on different servers

No. 

Very short answer, but on the surface, it is illegal to run more than one instance on one licence (it breaches your contract with Atlassian)

• If you have multiple Production systems, you need a licence for each one.
• If you are clustering many servers, but they all run the same Jira, then you need a single Data Centre licence.
• If you have one Production system, but then several other systems to run support/development/testing/failover for that single system, then you can use the "development" licence that comes with your Production licence to run them.
