I can't remove specific CSS and JS from the WP_HEAD. Please, help?

Hello everyone.
I’m trying to remove some specific lines from the WP_HEAD. Now my header looks following way:

<link rel='stylesheet' id='bootstrap-css'  href='/themes/wp-e/css/bootstrap.css?ver=4.2.2' type='text/css' media='all' />
<link rel='stylesheet' id='bootstrap-responsive-css'  href='/themes/wp-e/css/bootstrap-responsive.css?ver=4.2.2' type='text/css' media='all' />
<link rel='stylesheet' id='style-css'  href='/themes/wp-e/style.css?ver=4.2.2' type='text/css' media='all' />
<link rel='stylesheet' id='prettyPhoto-css-css'  href='/themes/wp-e/css/prettyphoto.css?ver=4.2.2' type='text/css' media='all' />
<link rel='stylesheet' id='custom-options-css'  href='/themes/wp-e/css/options.css?ver=4.2.2' type='text/css' media='all' />
<link rel='stylesheet' id='oswald_google-fonts-css'  href='https://fonts.googleapis.com/css?family=Oswald%3A400%2C300%2C700&subset=latin%2Clatin-ext&ver=4.2.2' type='text/css' media='screen' />
<link rel='stylesheet' id='thumbs_rating_styles-css'  href='/plugins/rating/css/style.css?ver=1.0.0' type='text/css' media='all' />

<script type='text/javascript' src='/js/jquery/jquery.js?ver=1.11.2'></script>
<script type='text/javascript' src='/js/jquery/jquery-migrate.min.js?ver=1.2.1'></script>
<script type='text/javascript' src='/plugins/q2w3-fixed-widget/js/q2w3-fixed-widget.min.js?ver=4.0.6'></script>
<script type='text/javascript' src='/plugins/rating/js/general.js?ver=4.0.1'></script>

I need to delete all of this, but I am not good at coding and all I know is that I have to put the

remove_action( 'wp_head', '???' );

But I have no idea what to put instead of ‘???’…

Please can anyone help?
