How can I shuffle grid elements without ruining the layout?

Question

As you can see in the example I have 6 elements "other-news" (colored Fuchsia) on the right side of the grid stacked in 3x2 format. I want to be able to bring them to the left side and keep them together in this 3x2 format. I tried to switch the order with the 2 elements class="articles secondary-stories" (colored coral red) (they have to go to the right side) by doing a copy/paste but this ruins my layout. How can I place the 6 elements to the left side and keep them together like in the original layout? Click "expand snippet" or "Full page" for better viewing the layout.
