In an AcroForm (non XFA) PDF form, all the fields with the same name
share a single value. In theory. iText doesn't support this very well,
but it doesn't prevent it either. iText won't create a parent field for
the value and make the existing fields children of that value, but it
also will use a single entry for the
AcroFields.getFieldItem("foo").getValue(n).
At any rate, combining multiple forms is one of the primary uses of
PdfStamper's flattening ability:
For Each Form
Set the field values
Flatten
Append flattened PDF to combined pdf
