Why each option
Meeting all high-availability requirements while keeping SQL AlwaysOn on dedicated servers requires a minimum of 4 servers in a SharePoint 2013 farm.
Two servers cannot satisfy the requirement because losing one server would take down either the SharePoint tier or the SQL tier entirely.
Three servers cannot meet the constraint that SQL must be on dedicated hardware separate from SharePoint while still providing full redundancy for both tiers.
To satisfy the single-server-failure tolerance requirement, at least two SharePoint servers are needed to provide redundancy for the application and Web Front End roles, including redundant search components distributed across them. The SQL AlwaysOn Availability Group requires a minimum of two SQL Server nodes to provide database-level high availability. Because SharePoint servers and SQL nodes must be on separate machines, the minimum total is 2 SharePoint servers plus 2 SQL servers, equaling 4 servers.
Five servers exceed the minimum; four servers are sufficient to meet all stated availability and separation requirements.
