Arrays in C# are zero based, so you need to start your iteration at 0 and not 1.

private void LoadDataToListview()
{
    var fileLines = File.ReadAllLines(@"E:\SCD_Project\Theory Assignments\A2\WindowsFormsApp1\WindowsFormsApp1\addressBook.txt");
    var groupSize = 8;
    //lineval = fileLines.Length;
   
    // start iterating at 0
    for (int i = 0; i < fileLines.Length; i += groupSize)
    {
        S3_manageAddress_listview.Items.Add(
            new ListViewItem(new[]
            {
                fileLines[i],
                fileLines[i + 1],
                fileLines[i + 2],
                fileLines[i + 3],
                fileLines[i + 4],
                fileLines[i + 5],
                fileLines[i + 6],
                fileLines[i + 7],
        }));
    }
}
