Hello Tia
For the top padding you could change it through customizer.
Go to dashboard > appearance > customize > home section > Our Featured Section > find “Section Padding Setting” change the top padding as per your requirement we changed it for you though you may check.
About the gap in between the content: It is occurring because there is an equal height script added in the theme for all the boxes which means if any one of the content is more than the other then all the boxes will inherit its height, so you will need to put equal content in each box.
Thank you
