To analyse the columns where object names can appear in any column BUT they DO NOT repeat in the same column.
if the object name appear once = 1
if repeat twice = 2
if repeat thrice = 3


NOTE:
1. Column  A B C E - in text format, F - in numeric format
2. Object name can appear more than once (but of course less than or equal to 3 times) in different COLUMN each.
3. Object name will NOT be repeated in the same column.
4. Object name, if repeated in each column may appear in different rows.

VLOOKUP works in sequence but the search for my case is all jumbled.

Hi, ceneiqe.

I'm not sure I've correctly understood your requirements as I came up with slightly different results (highlighted) to yours. The formula (for the first row)...
=SUM(COUNTIF(A:A,E2)>0,COUNTIF(B:B,E2)>0,COUNTIF(C:C,E2)>0)

your formula looks right. for example ABC1 appear 3 times in 3 diff column thus the code is 3. i put 1 as i counted wrongly. the right result =3 which you got it, same concept for those you have highlighted in red.

but let me run through with the actual data again, thks.

for column E,  it is manually type out, is it possible to summarise column E via macro and then get the results in F?

ceneiqe,

Is the attached what you're looking for? The macro is...
Option Explicit

Sub GetUniqueSets()
Dim xCell As Range
Dim xCollUnique As Collection
Dim i As Long
Dim xLastRow As Long

Sheets("Sheet1").Activate
xLastRow = ActiveSheet.Range("A1").SpecialCells(xlLastCell).Row 'Lazy way to determine no. of rows of sets. - could result in _lots_ of empty cells being checked.
If xLastRow < 2 Then
    MsgBox ("No data for sets found. Run cancelled.")
    Exit Sub
End If

Range("E2:F" & xLastRow).ClearContents 'in case there's old data.

Set xCollUnique = New Collection

'Build a collection of unique non-blank values...
For Each xCell In Range("A2:C" & xLastRow)
    On Error Resume Next
        If CStr(xCell.Value) <> "" Then _
            xCollUnique.Add xCell.Value, CStr(xCell.Value)  'collection is indexed so if a value already exists then it won't be added.
    On Error GoTo 0
Next xCell
    
If xCollUnique.Count = 0 Then
    MsgBox ("No non-blank data for sets found. Run cancelled.")
    Exit Sub
End If
    
' Output unique values...
For i = 1 To xCollUnique.Count
    Cells(i + 1, 5).Value = xCollUnique(i)
Next i
    
'Sort unique values...
Range("E2:E" & xCollUnique.Count + 1).Sort Range("E2"), xlAscending, , , , , , xlNo
    
' Calculate no. of entries for each unique value...
With Range("F2")
    .Formula = "=SUM(COUNTIF(A:A,E2)>0,COUNTIF(B:B,E2)>0,COUNTIF(C:C,E2)>0)"
    .Copy Destination:=Range("F2:F" & xCollUnique.Count + 1)
End With
With Range("F2:F" & xCollUnique.Count + 1)
    .Copy
    .PasteSpecial Paste:=xlValues
End With
    
Range("A2").Activate
Application.CutCopyMode = False
    
End Sub
