using System.Linq;
using System.Text;
using System.Windows.Forms;
using iTextSharp.text;
using iTextSharp.text.pdf;
using System.IO;

namespace PDFCreater
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{
for (int i = 0; i < 3; i++)
{
//Document document = new Document(PageSize.A4.Rotate(), 0, 0, 5, 0);
Document document = new Document(PageSize.A4.Rotate());
PdfWriter.GetInstance(document, new FileStream("E:/a" + i + ".pdf", FileMode.Create));
document.Open();
Paragraph p = new Paragraph("Test:: " + i);
document.Add(p);
document.Close();
}

MessageBox.Show("complete");
}
}
}

using System.IO;
using iTextSharp.text;
using iTextSharp.text.pdf;

class Program
{
    static void Main(string[] args)
    {
        using (Stream inputPdfStream = new FileStream("input.pdf", FileMode.Open, FileAccess.Read, FileShare.Read))
        using (Stream inputImageStream = new FileStream("some_image.jpg", FileMode.Open, FileAccess.Read, FileShare.Read))
        using (Stream outputPdfStream = new FileStream("result.pdf", FileMode.Create, FileAccess.Write, FileShare.None))
        {
            var reader = new PdfReader(inputPdfStream);
            var stamper = new PdfStamper(reader, outputPdfStream);
            var pdfContentByte = stamper.GetOverContent(1);

            Image image = Image.GetInstance(inputImageStream);
            image.SetAbsolutePosition(100, 100);
            pdfContentByte.AddImage(image);
            stamper.Close();
        }
    }
}

You can try using AnnBatesStamp to add the image logo into the created PDF file. This will also allow you to control the position of the logo. Here is an example and documentation you can build on:
private void AddWatermark(RasterImage image)
{
   using (AnnBatesStampComposer batesStampComposer = new AnnBatesStampComposer())
   {
      AnnBatesStampComposer.RenderingEngine = new AnnWinFormsRenderingEngine();
      AnnContainer batesStampContainer = new AnnContainer();
      batesStampContainer.Mapper.MapResolutions(image.XResolution, image.YResolution, image.XResolution, imag e.YResolution);
      batesStampContainer.Size = batesStampContainer.Mapper.SizeToContainerCoordinates(LeadSizeD.Create(image .Width, image.Height));

      using (AnnBatesStamp batesStamp = new AnnBatesStamp())
      {
         batesStamp.HorizontalAlignment = AnnHorizontalAlignment.Left;
         batesStamp.VerticalAlignment = AnnVerticalAlignment.Top;

         string imageFile = @C:\watermarks\input.png; // logo image to add
         batesStamp.Logo.Picture = new AnnPicture(imageFile);
         batesStampComposer.Stamps.Add(batesStamp);
         batesStampComposer.TargetContainers.Add(batesStampContainer);

         RasterImage watermarkedImage = null;
         watermarkedImage = AnnBatesStampComposer.RenderingEngine.RenderOnImage(batesStampContainer, image).C lone();
     RasterCodecs codecs = new RasterCodecs();
     codecs.Save(watermarkedImage,@"C:\files\output.pdf", RasterImageFormat.RasPdf, 0); // Output PDF with watermark
      }
   }
}

For adding image to you PDF document it is recommanded to use some tird party sdk which gives you more control over creading PDF and performing other operations. ByteScout PDF SDK is best for the said purpose. They have large number of examples for multiple operations on PDFusing C#. Below is the code for your problem.
for more details see this link https://bytescout.com/articles/pdf-sdk-c-images
// Create new document
            Document pdfDocument = new Document();
            pdfDocument.RegistrationName = "demo";
            pdfDocument.RegistrationKey = "demo";
            // Add page
            Page page = new Page(PaperFormat.A4);
            pdfDocument.Pages.Add(page);

            Canvas canvas = page.Canvas;

            // Add JPEG image and draw unscaled
            Image image1 = new Image("Image1.jpg");
            canvas.DrawImage(image1, 20, 20);

            // Add PNG image and draw reduced twice
            Image image2 = new Image("Image2.png");
            canvas.DrawImage(image2, 20, 520, image2.Width / 2, image2.Height / 2);

            // Add TIFF image and draw scaled disproportionately
            Image image3 = new Image("Image3.tif");
            canvas.DrawImage(image3, 270, 520, image3.Width / 2, image3.Height / 4);

            // Add GIF image and draw rotated 90 degrees and scaled
            Image image4 = new Image("Image4.gif");
            canvas.TranslateTransform(390, 650);
            canvas.RotateTransform(90);
            canvas.DrawImage(image4, 0, 0, image4.Width / 4, image4.Height / 4);

            // Save document to file
            pdfDocument.Save("result.pdf");

            // Cleanup
            pdfDocument.Dispose();

            // Open result document in default associated application (for demo purpose)
            ProcessStartInfo processStartInfo = new ProcessStartInfo("result.pdf");
            processStartInfo.UseShellExecute = true;
            Process.Start(processStartInfo);
