Use plugin multiple times

Unfortunately the Advanced Twitter Profile Widget Plugin does not use the WordPress Widget API and extend the WP_Widget class which would allow multiple instances of the widget.

Your best option is to find another Twitter Widget Plugin. There are hundreds available. I found one similar called Twitter WidgetWidget.

Install the Widget Logic Plugin which will create a meta box at the bottom of each widget for conditional statements on where to display it.

Drag one instance of the widget into the sidebar for each entertainer and add this to the widget logic box

is_page('page_name') using the slug from the page or use the page id.
