For Five Star Rating, the FAQ tells me you can leave out the shortcode from your articles (you added these to each article?), and then use echo five_star_rating_func('star') somewhere in your template. So this is a nice example of a plugin that offers both options.
For Simple Social, you need to disable the regular hook to the_content, and then call the function yourself. That could be done with the following code, which you can place in your theme’s functions.php (or at the top of your single.php, if you only want it gone on single pages):
remove_filter('the_content', 'simple_social');
Then, to display it again where you want it, you call simple_social() with an empty content string (be sure to do this in The Loop, since it relies on the global $post variable):
echo simple_social('');
