Hello, @TFS,
1.. By default there are only three rows available and you have to adjust the content in these rows. You can use the connection block feature of our theme in the header builder to add multiple elements to a widget. Please check this image for a better reference: https://postimg.cc/JD0L1YX8
2.. You can customize the header content by navigating to the Dashboard >> XSTORE >> Theme Options >> Header Builder and now set the contact widgets in the header and then customize it as per your requirements. See image: https://postimg.cc/TKbhx160
