what about: (this will unfortunately return the same row repeatedly, as many times as what there are age-columns < 20, but the last column (AgeGroup) will tell you which 'age' was < 20...)

SQL

SELECT *, 'First_Age' as 'AgeGroup'
FROM [dbo].[Advance_Sub_Tests]
WHERE First_Age < 20
UNION ALL
SELECT *, 'Second_Age' as 'AgeGroup'
FROM [dbo].[Advance_Sub_Tests]
WHERE Second_Age < 20
UNION ALL
SELECT *, 'Third_Age' as 'AgeGroup'
FROM [dbo].[Advance_Sub_Tests]
WHERE Third_Age < 20
UNION ALL
SELECT *, 'Fourth_Age' as 'AgeGroup'
FROM [dbo].[Advance_Sub_Tests]
WHERE Fourth_Age < 20
UNION ALL
SELECT *, 'Fifth_Age' as 'AgeGroup'
FROM [dbo].[Advance_Sub_Tests]
WHERE Fifth_Age < 20
