If next button is defined by page author, it depends on what they set it for.
Back button on browser is dependent on previous action. If its get, its going to be get, if it is post, its going to be post. That is why you see lot of web sites, where you search and go back, it asks whether you want to post again to get the result set.
Log out again could be either get/post depending on implementation.
Radio button selection is get.
