How to autogenerate changelog on spreadsheet?

I'm new using google spreadsheet. I'm trying to build device rental spreadsheet to track. When I change on the Borrower cell, then it will be generate to the changelog sheet.

I want to ask :

1. What should I write on the "appendRow" below?
2. When I paste "Boxed" text to the E1,E3,E4 cells in one action, is just add 1 row on the change log sheet. How to record all paste action on multiple cell (including random cell)?

The cell :
"No"    "Phone"    "Code"   "Price"   "Borrower"
 1      Iphone-X     1234      25$       John
 2      Iphone-8     1235      20$       Boxed
 3      Iphone-7s    1236      15$       Lina
 4      Iphone-6s    1237      10$       Michael

function onEdit(e) {  

// This script records changes to the spreadsheet on a "Changelog" sheet.
// The changelog includes these columns:
// "Timestamp", "Sheet", "Cell", "Type", "Old Value", "New Value", "User"
// Users are logged by email address.

var sheet = e.source.getActiveSheet();
      if (sheet.getName() !== 'All Device'|| e.range.getColumn() != 5)
        {
          return;
        }

      var ss = SpreadsheetApp.getActiveSpreadsheet();
      ss.toast("Running Script..", "Status");
      var ssdevice = ss.getSheetByName('All Device');

      var cell = SpreadsheetApp.getActiveRange();
      var d = new Date(); var timeStamp = d.getTime(); 
      var date = Utilities.formatDate(new Date(), "GMT+7", "dd MMMM yyyy - HH:mm:ss")
      var endDate = date

      var logdate = Utilities.formatDate(new Date(), "GMT+7", "- MMMM yyyy");
      var logendDate = logdate
      var changelogSheetName = "Log " + logendDate;

      var currentSheet = ss.getActiveSheet();
      var currentSheetName = ssdevice.getName();
      var newValue = cell.getValue();

      if (currentSheetName == changelogSheetName) return;
      var changelogSheet = ss.getSheetByName(changelogSheetName);

      if (changelogSheet == null) {

      changelogSheet = ss.insertSheet(changelogSheetName, ss.getNumSheets());

        Utilities.sleep(2000); // give time for the new sheet to render before going back

        ss.setActiveSheet(currentSheet);    
        changelogSheet.getRange('A1:F1').setBackground('#E0E0E0');
        changelogSheet.appendRow(["No", "Device", "Code", "Price", "Status", "Timestamp"]);
        changelogSheet.deleteColumns(8,19);
        changelogSheet.setFrozenRows(1);
        changelogSheet.setColumnWidth(1, 30);
        changelogSheet.setColumnWidth(6, 170);
        changelogSheet.setColumnWidth(7, 170);
        changelogSheet.protect();
      }

      changelogSheet.appendRow([ changelogSheet.getLastRow(), ..... , ..... , .... , ..... , endDate ]); 
      ss.toast("Done. Task has completed.", "Status", 1);
  }
