Is it ok to use text area for multiple subjects?

When user is answering question with radio buttons that opens new more specific questions. Is it bad idea to wrap those questions in one text area?

In my case user want might add multiple "compensations" so if used text fields there should be feature that enables adding multiple different "compensations". With text area there's no need for that feature because user can add all the information in one field.

I think text fields would be more clear in many case but in this one it might be better to use text area, or what you think?
