  But whats the way to mask data in SQL Server 2014 using Transact SQL.

  I want to mask number, Name and Email Address.

  you'll need to use good old fashioned strings or REPLACE functions.
  and you need to take into account the data types....you said number, but is it a string representing a number, so you can mask it?

  
/*
IDStarFirstNameStarLastNameEmail
0G***B*************@****.com
0M******R*************@****.com
0C********S***********@****.com
0R*****L*********@****.com
0S*****F*******@****.com
*/
;WITH MyCTE([ID],[StarFirstName],[StarLastName],[Gender],[Address1],[City],[State],[ZipCode])
AS
(
SELECT '1','Gene','Bergman','M','2615 Gainsboro Road',' Plantation','FL','33392' UNION ALL
SELECT '2','Michael','Roberts','M','42987 DarkSlateBlue Avenue',' Sunrise','FL','33335' UNION ALL
SELECT '3','Christoph','Spacey','M','27174 Green Avenue',' Sunrise','FL','33331' UNION ALL
SELECT '4','Robert','Leigh','M','44720 Seashell Avenue',' Sunrise','FL','33333' UNION ALL
SELECT '5','Samuel','Ford','M','39710 Cornsilk Road',' Sunrise','FL','33315'
)
SELECT
0 [ID],
LEFT([StarFirstName],1) + REPLICATE ('*',LEN([StarFirstName])-1) AS [StarFirstName],
LEFT([StarLastName],1) + REPLICATE ('*',LEN([StarLastName]) -1) AS [StarLastName],
REPLICATE ('*',LEN([StarLastName])) + '@****.com' AS Email
FROM MyCTE
