Question

In each column, after first 5 characters I need to add/replace next 5 characters with ‘*’ then add 10 more white spaces.

SELECT nameFirst, nameLast, number, fax 
FROM table_01

Expected result:-

Revol*****          Jenni*****          598-1*****          12345*****      
Jenit*****          Austi*****          598-1*****          12345*****          
Revol*****          Jenni*****          598-1*****          12345*****

Thanks.

This should do it.

SELECT 
   LEFT(nameFirst,5) + '*****          ',
   LEFT(nameLast,5) + '*****          ',
   LEFT(number,5) + '*****          ',
   LEFT(fax ,5) + '*****          '
FROM table_01

If you think you might want to use a variable later for the number of * and space characters, this technique might be better (and more readable) but uses keywords that are specific to tSQL:

SELECT 
   LEFT(nameFirst,5) + REPLICATE('*',5) + SPACE(10),
   LEFT(nameLast,5) + REPLICATE('*',5) + SPACE(10),
   LEFT(number,5) + REPLICATE('*',5) + SPACE(10),
   LEFT(fax ,5) + REPLICATE('*',5) + SPACE(10)
FROM table_01

Update per your comment
Assuming you want extra *’s for names with <5 characters. Here is an approach that should work.

SELECT 
   LEFT(nameFirst + replicate('*',5),5) + replicate('*',5) + SPACE(10)
   ...
FROM table_01

It is a little sneaky, but it avoids a longer inline conditional.
