Hi,

1/ For include banner in left & right of the logo - this theme doesn't support for this feature.

I recommend you use Header Style 3 like this: http://prntscr.com/rczeq8

And include the banner on the right side.

You can change the header style via Customize > Logo and Header Options > Header Layout.

And check options for banner for header style 3 there.

2/ For include banner below the slider, please check option for it via Customize > Homepage Options > Add Google Adsense/Custom HTML Code Below Featured Slider

You can fill HTML code for your banner there.

Best Regards,
