Customizing Top Header

Hello, I have a few questions regarding the top header: -Is there a way I can add text to the top header for every page on my website? I need to add the shop address and hours. -Is there a way to add social media buttons to the top header as well, versus them being in the footer on the bottom of every page. -Can I adjust the size of the header? Its a very large white space and takes up a lot of room. It would be nice to minimize the width. We currently use High Responsive. If needing to upgrade to the High Responsive Pro is necessary, please let me know. Thanks, The Spokehouse
