--Test Data
CREATE TABLE YourTable
    ([col] int, [col2] int, [col3] int, [col4] varchar(13), [col5] varchar(6), [col6] varchar(6), [col7] varchar(10), [col8] varchar(7), [col9] varchar(10))
;

INSERT INTO YourTable
    ([col], [col2], [col3], [col4], [col5], [col6], [col7], [col8], [col9])
VALUES
    (4, 4, 4, 'Home Threatre', 'Area', 'Deepak', 'Gram', 'CCAA2', 'Inches'),
    (5, 5, 4, 'Home Threatre', 'Area', 'Rahul', 'Inches', NULL, '0'),
    (6, 6, 5, 'Home Threatre', 'length', 'a1', 'Gram', 'ann2', 'IClogram'),
    (7, 7, 5, 'Home Threatre', 'length', 'bl', 'Centimeter', 'bnn2', 'Meter'),
    (8, 8, 6, 'Home Threatre', 'Width', 'zzl', 'Centimeter', 'z222', 'Centimeter'),
    (9, 9, 6, 'Home Threatre', 'Width', ')71', 'Milimeter', 'y222', 'Milimeter'),
    (10, 10, 6, 'Home Threatre', 'Width', 'x211', 'Centimeter', NULL, '0'),
    (11, 11, 3, '2PinSwitch', 'A3pin3', 'sddsf', 'Meter', 'dsfsctf', 'Milimeter'),
    (12, 12, 3, '2PinSwitch', 'A3pin3', 'dddd', 'Centimeter', NULL, '0')

--Query Script
select [col], [col2], [col3], [col4], 
  case when rank = 1 then
    [col5]
  else
