making it so that documents can be fillled out

Hi,
Below I've provided links to several documents. The client would like for customers to be able to fill out these documents with merge fields and be able to print them/email them. We would predefine the merge fields and the customer would fill out a form to pre populate these. Are there any plugins that can do this either on wordpress or allow them to be filled out on a cloud provider like dropbox or google docs?
