Dear Carla,
Each site in a multisite install is treated as an individual site. You can enable the plugins site-wide, but each site will have its own data.
However, there are ways to distribute settings via the theme, by embedding types in your theme:
http://wp-types.com/documentation/embedded-types-and-views/embedding-types/
Or you can use the module manager to redistribute your settings:

Please let me know if you are satisfied with my answer and if I can help you with any other questions you might have.
Regards,
Caridad
