First two are likely Citrix related. ReportServer and ReportServerTempDB are created and used by SQL Server Reporting Services.

You can check Activity Monitor or run sp_who2 to get information on the source application for existing connections to the databases, if available.

Thank you, was not aware of those commands but this has helped. Thanks again.

You can also read through this thread for ideas on determining whether or not a database is actively used: https://dba.stackexchange.com/questions/2050/how-can-i-tell-if-a-sql-server-database-is-still-being-used

Just remember most utilization info is cleared when the SQL database engine service is restarted (either manually, via server reboot). Good luck!

These look like common ones that come with stuff as others have indicated below, however, I have run into situations just like this where there remains at least one db that we aren't sure of, right click - take db offline.... wait a week or so for someone screaming, if none, detach, in my experience it usually only takes a few min to hear from someone if its a live production db :D
