Click the "x" at the top of the widget box. Make sure you remove them from your profile, too, if you want them. If you have already removed them from your homepage but want to removed them from your profile (which looks different then your homepage) go to "view my profile" and check.
I have seen a lot of profiles that have endless widgets that are repeats or not set up because people don't realize we see something different then you do.
