1 - To add a new position, you can follow my suggestion here: https://www.joomlart.com/forums/d/31281-module-published-in-header-position-not-getting-displayed-in-gk-issues/7
In that topic, I suggest to add a new position and load that new position in to the layout of template, you can apply the same to GK University template you're using. Of course, the class / style will be different and you must customize style for it.
2 - For the alignment of sidebar, it seems that you removed module above this part so it seems to be mis-aligned with above slideshow, I just added this custom css:
#gkSidebar {padding-left: 37px !important;}
to the override.css in template to fix it.
Kindly check.
