   The are essentially combinations of classical molding elements or components. E.g., in the last image top to bottom...torus, scotia/cavetto, fillet, torus, on plinth/base. Difficult to make out exactly the details of images 1 and 2....looks somewhat like a torus, then series of ogees with fillets. The angled piece in 4 is functioning as a "bed mold" and this type is sometimes called a splay. The following 2 links are to a couple of books that are very useful in getting the history and nomenclature for these designs...and how they are composed. The first is an important one. https://books.google.com/books/about/The_Theory_of_Mouldings.html?id=XWxTAAAAMAAJ&printsec=frontcover&source=kp_read_button&hl=en&newbks=1&newbks_redir=0&gboemv=1#v=onepage&q&f=false

   Follow up question - where can I purchase the types of moldings you identified? I’ve looked at Home Depot and lowes and haven’t been successful.

   A few things. As mentioned below often times a complex molding is assembled from parts. That said I worked for a time as a draftsman in a custom furniture shop and we basically had a shaper bit custom made for each project with compound molded elements that weren't off the shelf. There were a few reasons why. One, it was a time saver. Two, you could get the required molding made exactly to the spec. Three, a piece of furniture "sometimes" has durability requirements where you wouldn't want a bunch of parts depending on the location/application of the molding. Note, your 4th picture from top on second look has what "appears to be" a thumbnail type shape on top with quarter round below - these are common in bits of course. The hollow below appears still to be a type of scotia - a hollow of compound curves. You will not find a bit/head to cut that off the shelf. So it would be difficult to find the parts to recreated it exactly - although you could use a box core bit to "approximate" it. The 2nd image could be probably made from two moldings off the shelf - the lower two - but probably not the top piece. That would be hard to find ready made i.m.o. Lastly, sometimes I will use a large single piece (large crown or base e.g.) off the shelf made up of a number of elements and "cut out" the elements required and can create the desired final molding. Sometimes I will use single/smaller elements of off the shelf and assemble a compound molding. Or do a combination of these two things. In the NYC area we use a co. Dykes Lumber for very basic paint grade (and some Oak) moldings that can be used to build up a compound molding. They have a PDF of the molding catalog and they ship.

   Check with Van Dyke Restorers. Good resource.

   Many of these are not cut in one pass, and most are not even one piece.
   Instead they are built up from the elements either pass by pass or separately cut pieces glued together.
   The challenge is working out how to copy the profile with the minimum number of router bits.
