Validate Columns

Hello - How can I create a measure or column to validate all the columns of a table as

If Column 1 is not blank and contains 3 characters    &

If Column 2 is not blank and contains 3 characters    &

If Column (Date) is not blank and contains a date    & 

If Column (Time 1) is not blank and contains time    & 

If Column (Time 2) is not blank and contains time 

If all columns are validated return Valid else Invalid.
