Answer 1

    SELECT a.PositionName,COUNT(a.ApplicationNo) AS           
NoOfApplications,apl1.Qualified,apl2.DisQualified
FROM APPLICATION a
INNER JOIN (
SELECT PositionName, COUNT(ApplicationNo) AS Qualified
FROM APPLICATION
WHERE EligibleStatus1=1 AND  
EligibleStatus2=1 
GROUP BY PositionName
)apl1 ON a.PositionName=apl1.PositionName
INNER JOIN (
SELECT PositionName, COUNT(ApplicationNo) AS DisQualified
FROM APPLICATION
WHERE EligibleStatus1=1 AND  
EligibleStatus2=1 
GROUP BY PositionName
)apl2 ON a.PositionName=apl2.PositionName
GROUP BY PositionName ORDER BY PositionName  

Answer 2

SELECT      Positionname,
            Count(NoOfApplication) AS NoOfApplications,
            Max(COUNT1)            AS Qualified,
            Max(COUNT2)            AS Diqualified
FROM        APPLICATION A
CROSS APPLY (SELECT Count(NoOfApplication) AS COUNT1
             FROM   APPLICATION A
             WHERE  EligibleStatus1 = 1
                    AND EligibleStatus2 = 1)B
CROSS APPLY (SELECT Count(NoOfApplication) AS COUNT2
             FROM   APPLICATION A
             WHERE  EligibleStatus1 = 2
                     OR EligibleStatus2 = 2)C
GROUP       BY PositionName

Answer 3

as you are looking for Summary result then by using Case and Sum we can get desired Result basing on your assumpted Data

select PositionName,
sum(case when EligibleStatus1 = 1 AND EligibleStatus2=1 then 1 else 0 end) AS Qualified,
sum(case when EligibleStatus1  = 2 OR EligibleStatus2=2 then 1 else 0 end) AS DisQualified,
count(ApplicationNo) 
from APPLICATION 
GROUP BY PositionName
ORDER BY PositionName
