OK. What is your question?

Do either of these give you what you need?

--ONE ROW PER NAME WITH COUNT
SELECT firstlastmerged,
       COUNT(firstlastmerged) AS Cnt
FROM   dbo.YourTable
GROUP  BY firstlastmerged

--REPEATED NAMES WITH REPEATED COUNT
SELECT firstlastmerged,
       COUNT(*) OVER (PARTITION BY firstlastmerged) AS Cnt
FROM   dbo.YourTable

A lot of us won't open attached spreadsheets for many reasons. Please see the article at the first link in my signature line below for the preferred method of using readily consumable data.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

Here is the query to insert the data in table.

-- Step 1: Create the table

CREATE TABLE sat_temp (

Domain NVARCHAR(255),

[Required Result] INT

);

-- Step 2: Insert the data

INSERT INTO sat_temp (Domain, [Required Result])

VALUES

('AlissaParteemarvin.com', 10),

('DanielOoiocbc.com', 5),

('GargPrashantocbc.com', 1),

('GaryKeildurangotrain.com', 2),

('GuSuyangsdic.com.cn', 2),

('GuSuyangsdic.com.cn', 2);

Need a query to get the result which I had mentioned in column [Required Result]

If you're going to create a temp table, at least make it temporary!

DROP TABLE IF EXISTS #sat_temp;

CREATE TABLE #sat_temp
(
    Domain NVARCHAR(255)
);

INSERT #sat_temp
(
    Domain
)
VALUES
('AlissaParteemarvin.com')
,('AlissaParteemarvin.com')
,('AlissaParteemarvin.com')
,('AlissaParteemarvin.com')
,('AlissaParteemarvin.com')
,('AlissaParteemarvin.com')
,('AlissaParteemarvin.com')
,('AlissaParteemarvin.com')
,('AlissaParteemarvin.com')
,('AlissaParteemarvin.com')
,('DanielOoiocbc.com')
,('DanielOoiocbc.com')
,('DanielOoiocbc.com')
,('DanielOoiocbc.com')
,('DanielOoiocbc.com')
,('GargPrashantocbc.com')
,('GaryKeildurangotrain.com')
,('GaryKeildurangotrain.com')
,('GuSuyangsdic.com.cn')
,('GuSuyangsdic.com.cn');

SELECT st.Domain
      ,ct = COUNT (st.Domain)
FROM #sat_temp st
GROUP BY st.Domain;

@sathishkm-2

Did either of Ed B's solutions work for you?

If not, could you post what the output should look like using the test data you've provided? I'm also not sure what your request actually is.
