Assuming that you have a pure AcroForm and not a hybrid form as I indicated in my comment, this is how you change the quadding of a field:

AcroFields form = stamper.getAcroFields();
AcroFields.Item item;
item = form.getFieldItem("fieldLeft");
item.getMerged(0).put(PdfName.Q, new PdfNumber(PdfFormField.Q_LEFT));
item = form.getFieldItem("fieldCenter");
item.getMerged(0).put(PdfName.Q, new PdfNumber(PdfFormField.Q_CENTER));
item = form.getFieldItem("fieldRight");
item.getMerged(0).put(PdfName.Q, new PdfNumber(PdfFormField.Q_RIGHT));

The quadding isn't part of the field flags as you wrongly assumed. It's and entry of the widget annotation dictionary.
