MS SQL: complex query that has multiple queries in one

MSSQL
Have 1 database, need to pose four queries to create a single result. The first query will return "Application" name.

;WITH group1 AS
(
SELECT [CLASS] AS EXTENSION, [CLASSNAME] AS TYPE, [KEYNAME] AS KIND, [KEY]
   FROM SYSTEM WHERE KEYNAME = '#APPLICATION'
)

Second query collects "VBOX" name

, group2 AS
(
SELECT [CLASS] AS EXTENSION, [CLASSNAME] AS TYPE, [KEYNAME] AS KIND, [KEY]
   FROM SYSTEM WHERE KEYNAME = '#VBOX'
)

Third uses the two group to present a result with single row per record.

SELECT * FROM group1
   JOIN group2 on group1.EXTENSION = group2.EXTENSION
      ORDER BY group1.EXTENSION ASC

These work well but my issue is the columns present "numeric" values for the "KEY" columns. So I need to re-query the "SYSTEM" table to find matching data that match the [KEY].numeric result.

EXTENSION   TYPE   KIND   KEY   EXTENSION   TYPE   KIND   KEY
11011121600   VMX   #APPLICATION   AF71B74D301842C   11011121600   VMX   #VBOX   BC56379D-B99C-4058-A563-E0CE3D0C1480

The above is a sample of the result. Want to query the "SYSTEM" table looking for more data regarding each row's final KEY column. Example looking for "BC56379D-B99C-4058-A563-E0CE3D0C1480". The result will be two column with EXTENSION and the result of the forth query.

As there are 186 rows return by the first three linked queries there will 186 row of two columns in the final result.
Any help would be appreciated.
