Very easy to create for the top left on the page that you linked to ... either by creating a slab with magic wand, and tilting it up, or by using a complex profile and a short beam. The others require a few extra bits and pieces to assemble.
Qualifying 'very easy' - easiest if you have things from that page as dwg or other actual linework. Next easiest if you have Adobe Illustrator or something that can convert an image to vector linework ... and then save as dwg (etc). (The conversion won't work really well with a low quality jpg though.)
