Simple Social Icons is an easy to use, customizable way to display icons that link visitors to your various social profiles. With it, you can easily choose which profiles to link to, customize the color and size of your icons, as well as align them to the left, center, or right, all from the widget form (no settings page necessary!).
*Note: The simple_social_default_glyphs filter has been deprecated from this plugin.

To use this plugin – your theme (or child theme) must support it. 
To display additional profiles for user you just need to use native WordPress function <code>the_author_meta( 'profile-name' )</code> where ‘profile name’ can be ‘twitter’, ‘facebook’, ‘googleplus’, ‘instagram’, ‘pinterest’.
Code example (with Font Awesome Icons):
<pre><code><?php
 $prefix_twitter_url = get_the_author_meta( 'twitter' );
 $prefix_facebook_url = get_the_author_meta( 'facebook' );
 $prefix_googleplus_url = get_the_author_meta( 'googleplus' );
 $prefix_instagram_url = get_the_author_meta( 'instagram' );
 $prefix_pinterest_url = get_the_author_meta( 'pinterest' );
?>
<?php if ( ! empty( $prefix_twitter_url ) ) : ?><a href="<?php the_author_meta( 'twitter' ) ?>"></a><?php endif; ?>
<?php if ( ! empty( $prefix_facebook_url ) ) : ?><a href="<?php the_author_meta( 'facebook' ) ?>"></a><?php endif; ?>
<?php if ( ! empty( $prefix_googleplus_url ) ) : ?><a href="<?php the_author_meta( 'googleplus' ) ?>"></a><?php endif; ?>
<?php if ( ! empty( $prefix_instagram_url ) ) : ?><a href="<?php the_author_meta( 'instagram' ) ?>"></a><?php endif; ?>
<?php if ( ! empty( $prefix_pinterest_url ) ) : ?><a href="<?php the_author_meta( 'pinterest' ) ?>"></a><?php endif; ?>
</code></pre>
