#1. Compare to winter vetch, Vicia villosa ssp. varia. http://tenn.bio.utk.edu/vascular/da...ID=vi_vill_vari&PhotographerNameID=Bart Jones #2 looks to me like the seed pods of a perennial geranium (or erodium, I suppose). If you compare to the species present in the site above, you may find it. #3 look like a cereal grain, probably a bearded wheat (just like your photo label says).
