The first one is Cosmarium granatum, the second Cosmarium botrytis var.
The last one is not a desmid because it has more than 2 segments.

Beautiful images.
The first two have been IDed and the third looks like a slightly immature Coleochaete, which along with Chara, is one of the most advanced genus in the Charaphyceae. There should be a long seta or hair produced by the central cell.
Hope this helps,
Donald
