According to: https://docs.microsoft.com/en-us/sql/sql-server/maximum-capacity-specifications-for-sql-server?view=sql-server-ver15:

50 instances on a stand-alone server.

25 failover cluster instances when using a shared cluster disks as storage.

50 failover cluster instances with SMB file shares as the storage option.
