    {
        //Create document  
        pdfDoc = new Document(PageSize.A4, 25, 25, 25, 15);
        //Create a PDF file in specific path  
        PdfWriter pdfWriter = PdfWriter.GetInstance(pdfDoc, new FileStream(System.Web.HttpContext.Current.Server.MapPath(fileName+".pdf"), FileMode.Create));

You should use PdfAppearance to set the checkbox(or radioButton, button, etc. )

Here's a full example

        public static void chkBoxesCreator()
        {  
           String[] texts = { "one", "two", "three" };

            using (var pdfDoc = new Document(PageSize.A4))
            using (var output = new FileStream(fileLoc, FileMode.Create))
                using (var writer = PdfWriter.GetInstance(pdfDoc, output))

            {

                {
                    pdfDoc.Open();                     

                    PdfContentByte cb = writer.DirectContent;
                    Rectangle _rect;
                    PdfFormField _Field1;

                    PdfAppearance[] checkBoxes = new PdfAppearance[2];
                    //set first  checkBox style
                    checkBoxes[0] = cb.CreateAppearance(20, 20);
                    checkBoxes[0].Rectangle(1, 1, 18, 18);
                    checkBoxes[0].Stroke();

                    //set second  checkBox style
                    checkBoxes[1] = cb.CreateAppearance(20, 20);                  
                    checkBoxes[1].Rectangle(1, 1, 18, 18);
                    checkBoxes[1].FillStroke();

                    RadioCheckField _checkbox1;

                    for (int i = 0; i < texts.Length; i++)
                    {
                        _rect = new Rectangle(180, 806 - i * 40, 200, 788 - i * 40); //can be any location
                        _checkbox1 = new RadioCheckField(writer, _rect, texts[i], "on");
                        _Field1 = _checkbox1.CheckField;
                        _Field1.SetAppearance(PdfAnnotation.APPEARANCE_NORMAL, "Off", checkBoxes[0]);
                        _Field1.SetAppearance(PdfAnnotation.APPEARANCE_NORMAL, "On", checkBoxes[1]);
                        writer.AddAnnotation(_Field1);

                        ColumnText.ShowTextAligned(cb, Element.ALIGN_LEFT, new Phrase(texts[i], new Font(Font.FontFamily.HELVETICA, 18)), 210, 790 - i * 40, 0);
                    }

                    cb = writer.DirectContent;
                    pdfDoc.Close();
                }
            }
        }

PS The only problem i have that i couldn't use your font for some reason i was getting gibberish

Edit

You could even change you checkBox fill Color with(and you could make any more crazy thing like create a cross when the checkbox is checked)

  checkBoxes[1].SetRGBColorFill(255, 128, 128); //change fill color

And the output is(with SetRGBColorFill)
