From what I understand, you are trying to create a validation.

if(
   contains(
     local!duplicateCheck.error,
     "Duplicate Values Found"
   ),
   "This file contains one or more duplicate values.",
   ""
 )

In the code provided before replace the local variable used for getting the output with this.

Please find the below code. Made a sample code for your understanding. More efficient and simpler code can be created.

a!localVariables(
  local!doc: ri!doc,
  local!data: readexcelsheetpaging(
    excelDocument: ri!doc,
    sheetNumber: 0,
    pagingInfo: a!pagingInfo(startIndex: 2, batchSize: 5000)
  ).data.values,
  local!formatData: a!forEach(
    items: local!data,
    expression: if(
      a!isNullOrEmpty(fv!item[2]),
      {},
      a!map(
        name: fv!item[2],
        gender: fv!item[3],
        department: fv!item[4],
        tech: fv!item[5]
  )
  )
  ),
  local!duplicateCheck: a!forEach(
    items: local!formatData,
    expression: a!update(
      data: fv!item,
      index: "error",
      value: if(
        length(
          wherecontains(
            fv!item.name,
            local!formatData.name
          )
        )>1,
        "Duplicate Values Found",
        ""
      )
    )
  ),
  local!duplicateCheck

Could you elaborate more on what you are trying to do? Are you looking for duplicates on "No" and/or "col1" and/or "col2"? What are you expecting in error1/2/3? What does your current expression rule look like, and what have you tried for finding the duplicate values that is giving you difficulty?
