They are not used in everyday conversation, at least not anymore. They are for story telling, news, books, speeches, etc. "Compelled" is probably the most common though, and then I feel compelled to tell you that "appalling" probably comes next in line. Forgive my appalling lack of manners, but I can't think of a sentence at the moment for the other two. :) Seriously though, those examples are not everyday speech. People are simpler and less wordy.
These words add richness or formality to the sentence, depending on what you're trying to achieve, but are not necessary for successful conversations. You'll find these mostly on paper, in story telling, or speeches. Hope this helps! Great question.
