Hi,
I've got a few items that we're having trouble identifying.  Maybe you can help?   

The first one is listed as 10.125H x 16.750W x 4.750D - Unknown iron piece, possibly a blacksmith tool for shaping iron, consisting of an open quarter circle and a rhomboid shape at the point.

The second:4.750H x 11.375W x 15.250D - Thin flat strip of iron which is bent into a half-circle shape. From one end of the half circle the strip is bent straight out with a short 90 degree bend at the end. There are three holes in the half circle with iron bolts and square nuts. There are three additional holes in the straight part one of which has a bolt through it.

The third: 46.500H x 8.000W x 1.000D - Long rod of cast iron slightly bent at one end and terminating in a pointed hook. At the other end, the rod is looped. Attached to the loop at two chain links, to which is attached a large loop of iron.  ---This is not cast iron--

And the fourth (Doc5): 40.250H x 7.000W x 1.000D - Blacksmith tool consisting of a long rod of iron with one end bent at a 90 degree angle and the other end is spit into horns resembling a wrench.

Thanks for consideration.

I can't seem to open the pics.

Clearer, brighter pictures would help a lot.  The second metal piece in doc.3 (cf-nc 489) appears to be a spoke dog, although a different design than I'm used to seeing.  The tool at the top of doc.3 with the 90 degree angle is almost certainly a fire rake for working the fire in the forge.  I have a couple of these myself.

Thank you for the reply.  Unfortunately, these were the photos I got. 

Another suggested that the flat bar shaped into a semi-circle could be part of a fifth wheel for a buggy and the large iron piece with the quarter circle and rhomboid shape could be an less common swage.  The bent rod with the linked circle on one end and a hook on the other could be part of the bellows linkage.
