Answer 1

Your question is not very clear but as you told in comments, you can sum the count of 2 select statemets like below (assuming your select statements are working and returning integer values) and use this in your query.

select 
        (Select 
                        count(TABLE1.RECID) AS [ar3]
            from            TABLE1 left outer join 
                    TABLE2 ON TABLE2.ISSUEID = TABLE1.ISSUEID 
            where   TABLE1.STATUS = 4 
                    and TABLE2.NOTIFICATIONINDEP = 1
                    AND dateadd(second, TABLE1.CREATEDTIME, TABLE1.createddate) <= dateadd(hour, -1, @CURDATETIME) 
                    and dateadd(second, TABLE1.FinishedTime, TABLE1.FinishedDate) between dateadd(hour, -2, @CURDATETIME) and @CURDATETIME)
 +

        (Select 
                        count(TABLE.RECID) as [ar4]
            from            TABLE1 left outer join 
                    TABLE2 ON TABLE2.ISSUEID = TABLE1.ISSUEID
            where   TABLE1.STATUS = 3 and TABLE2.NOTIFICATIONINDEP = 1
                    and dateadd(second, TABLE1.createdtime, TABLE1.createddate) < dateadd(hour, -1, getdate()))
