Can I use the feeds module to import csv data to 2 different content type?
Unless anything has changed in the last couple of weeks, I don't think it's possible to set up one feed to import to multiple content types out of the box.  There's some discussion here.

That said, someone did mention the Feeds Node Helper module which apparently does allow this feature, although I'm no sure how robust it is.


  Feeds Node Helper is a collection of useful Feeds Import targets and
  Tampers. This is how book content can be imported and exported between
  Drupal sites. It provides helpers for the following:
  
  
  UUIDs
  Book parent based UUIDs
  Book Weights
  Node Types (by default Feeds just maps to 1 type, this allows multiple)
  


EDIT

If the module doesn't work, I don't see any reason why you couldn't simply set up two feeds that both use the same source CSV file; one for each content type.
