How many individual instances can be on a single physical machine?
You can install as many as 50 SQL Server instances on a Windows Server; obviously, we do not recommend this.

Only one of the SQL Server instances on a server can be the default instance.
Is it possible to have single database shared across multiple servers?

How to consolidate multiple databases in SQL Server?
This article mainly focuses on the consolidation type of hosting multiple databases on a single, highly available SQL Server instance and suggests a methodology of assessing the candidate databases.
