I am trying to write the following code to get all details and get output. but I am getting failed pls guide me to solve it.

Option Explicit

Sub CopyRows()
    Dim ws1 As Worksheet, ws2 As Worksheet
    Dim i As Integer, k As Integer
    Dim ws1LR As Long, ws2LR As Long

    Set ws1 = Sheets("input")
    Set ws2 = Sheets("output")

    ws1LR = ws1.Range("A" & Rows.Count).End(xlUp).Row + 1
    ws2LR = ws2.Range("A" & Rows.Count).End(xlUp).Row + 1

    i = 2
    k = ws2LR
    Do Until i = ws1LR
        With ws1
            .Range(.Cells(i, 1), .Cells(i, 18)).Copy
        End With

        With ws2
            .Cells(k, 1).PasteSpecial
            .Cells(k, 1).Offset(1, 0).PasteSpecial
        End With

        k = k + 2
        i = i + 1
    Loop
End Sub

I think the easiest way to achieve your goals is:

Sub prueba()


    Const adOpenStatic = 3
    Const adLockOptimistic = 3
    Const adCmdText = &H1

    Dim point2 As String
    Dim point3 As String

    Dim query As String

    Set objConnection = CreateObject("ADODB.Connection")
    Set objRecordset = CreateObject("ADODB.Recordset")

    objConnection.Open "Provider=Microsoft.ACE.OLEDB.12.0;" & _
        "Data Source=C:\Users\Daniel\Desktop\prueba.xlsx;" & _
            "Extended Properties=""Excel 8.0;HDR=Yes;"";"

    query = "Select cm.dear FROM [input$] as i inner join [cm$] as cm on i.house = cm.house where test is not null"

    objRecordset.Open query, _
        objConnection, adOpenStatic, adLockOptimistic, adCmdText

    'since query returns one row so:

    point2 = objRecordset.Fields.Item("dear") '<---- returns "dfd"

    objRecordset.Close

    query = "Select mm.moon FROM [input$] as i inner join [mm$] as mm on i.house = mm.house where test is not null"

    'following line cant return any value because there is not any house field on mm table
    objRecordset.Open query, _
        objConnection, adOpenStatic, adLockOptimistic, adCmdText

    point3 = objRecordset.Fields.Item("moon")


End Sub

All you should to know about this code, is how to write the proper query.

Pay attention to query variable, it's like a sql query, you can join several tables and look for a value where these two values in two fields (columns) are equal. That's because you cant run the second query, because there is not a field called house in mm table (accordingly to your example).
