@optimist and others asking about identifying unknown trees… it is very hard, particularly among American persimmons. I’ve walked through a persimmon orchard with probably 40 varieties of trees and while I could confidently identify kaki, hybrid and American trees by type, for the most part I couldn’t confidently identify specific cultivars except if they had unique characteristics to their fruit like Saijo or Giboshi for kaki, Prok for American persimmons and JT-02 for hybrids.
In terms of pictures of full trees, I don’t think that will provide any meaningful help. For instance a Prok in my yard looks very different in form/shape than one in my neighbors yard. Besides the large impact from pruning approaches, there are the influences of length of growing seasons, latitude, soil, etc.
Fruit comparisons will help, if your trees are fruiting, but even that is very hard among American persimmons, particularly since many trees have common genetics coming from Early Golden. I don’t grow it myself, but Lena was a wild find and has smaller fruit that will get more reddish when fully ripe. I find H-63a is flatter, but still slightly convex across the bottom, when compared directly to my Ruby, H-118, Barbara’s Blush and 100-46. H-63a seems to also get a little darker orange than the others, but I still couldn’t confidently identify any of these out of a group of unidentified fruit all on one plate. I might make some correct guesses, but not confident IDs.
In case you haven’t seen it, here is a PDF of the Claypool planting if that helps to at least see parentage of some of your trees.

For your hybrids, it should be easier, as long as you can single them out from the Americans by seeing the kaki influence. Fruit will help, but the leaves are often fairly different as well, most likely because the parentage is more varied. Luckily you only have three and I think they have some identifiable differences.
Here are some leaves from my Chuchupaka, which I find to be shorter, fatter and more truncated on the back edge (usually with recurve going into the leaf stem).
Fruit will be like an American in shape, but slightly taller than most, and should be deeper orange inside when ripe.
And here are some leaves on a young Bohzy Dar graft which are clearly different than Chuchupaka. These are more elongated and generally smaller than many of my pure Kaki grafts and other hybrids. Twigs are thinner as well and this tree is known to be fairly dwarf in stature. When it flowers, you will ultimately see male, female and bisexual flowers on the tree, although not necessarily when it is very young. You will also get a smaller fruit from the bisexual flowers, so you should see two sizes of fruits on the same tree.
I don’t currently have Sosnovskaya here (I have it at my in-laws), but if I remember correctly the leaf shape is sort of between the two and more like most of the other hybrids. I think when comparing leaves, growth and ultimately fruit you should be able to identify this compared to your other 2 hybrids. Fruit are roundish and average around 90g.
Hopefully this helps a bit, but I expect many of your trees will be difficult if not impossible to ID beyond an educated guess.
