For the footer, there are custom widget areas created for each column. These widget areas are created under Appearance > Widget Areas. They’re applied to your footer from Appearance > Theme Options > Layout > Footer. And you put widgets in them from Appearance > Widgets.
Specifically the widget with title “Get in Touch” you see in the demo used in that widget area is the “Theme Blvd Simple Contact” widget.
