I have built a form in Adobe InDesign with 45 text fields set to populate with the same LOT code. In Adobe InDesign, the font is 12 pt Arial regular in the PDF when you type in A2 hit tab and populate in all fields, the font is changing to Times roman.
Acrobat can do it, certainly. It seems like you should be asking over at the InDesign forums...
InDesign's form fields properties are not exported to the PDF, you must use Acrobat Pro to change text font, text size, etc.
The good news is that you can select multiple fields to edit their properties in one go.
