Oh, my! You have very lovely birds! This post is going to ramble a bit as I attempt to organize my thoughts. Fair warning.
I don't breed Orpingtons. I did have some blacks, but used them for project breedings with other breeds. They make fabulous, big, beautiful Easter eggers! And the blacks I had laid eggs like crazy, not huge eggs but lots of them, which is why I was outcrossing in the first place. The woman I got them from, bred for all traits including stellar egg production. I wish she was still breeding birds!
I'm a lover of colour in poultry, but not a very good student. Chicken genetics are beyond me except at the most basic level. I WANT to learn the technical details, but every time I try, I just can't seem to absorb anything. I'm stuck working at an intuitive level: If I stick x rooster with y hen, I will get x, xx, xy, yx, and maybe a and b. Just don't ask me to show my work.
So with my limited knowledge and experience in mind, I'll tell you some of what I intuit looking at your lovely birds, if you want to hear it, and hopefully more experienced breeders will correct where I have gone wrong.

Lemon cuckoo orpingtons for example, when I look at them, don't look 'lemon' to me at all; I think it's a washed-out buff (gold) due to a modifier, and not the same as true lemon, which I believe is gold and silver in the same feather. I'm really not sure, though, so keep that in mind :) With your "lemon lavenders" as you call them, the colour you call lemon looks identical to me to the 'lemon' in other import origin Orpingtons. If I recall correctly, Buff Orpingtons ARE/WERE used in North America to create/invigorate the "lemon" in colours imported, so it's very possible the breeder you got these from was outcrossing, or that these are throwbacks. Nothing wrong with that, as you have found out, you can get some fun colours!
I'm pretty sure I'm seeing some Columbian modifiers in the top two pictures, which sort of confirms to me that there's been some funky outcrossing going on in the past (there are buff lavender brahmas) but also makes me wonder if the birds in those two are not lavender, but light blue.
When I look at your "lavender splash", I'm not sure that's what you've got (self blue being very different from blue/splash/black) and I think it may be a very washed-out splash. If you breed splash together, you will get progressively faded and fewer splash markings until they seemingly disappear altogether. Lavender (self blue) is not the same as blue, which can come in all shades from very light, almost white, to almost black and every shade in between. To have a lavender splash, I think you would have to have a bird that has TWO copies of lavender, and also TWO copies of blue. It would be exceedingly difficult to find out if this is the case...but if you end up with a cockbird coloured like her, mash them together and keep notes on what hatches out! I also think she could be a throwback to a white progenitor some generations back. I think white Orpingtons (assuming the outcross was a white Orpington, and not a white Something Else) are recessive white, meaning, to my mind (again I may be wrong) that the white will eventually "breed out" if you're not selecting for it (e.g. eating all your "splash" chicks) BUT (in my limited experience), if the white comes from dominant white, (Leghorns come to mind, and I think Brahma are Dom White) it keeps popping up for freaking decades. White chicks with random coloured splashes hatch in with coloured chicks. Great if you're just like me and breeding some colourful birds for backyard beauties and the freezer, but if you want to work towards a variety of your breed, you have to be prepared to cull intensively. Dominant white throwbacks should never be used for breeding when trying to fix a colour, unless that colour is white. It's annoying. And sometimes, the only way to know, is to put a pair of birds together and hatch EVERYTHING. And then, put the hen with a different rooster, and hatch EVERYTHING. And then, put the first rooster with a different hen, and hatch EVERYTHING. And learn to like eating chicken two meals a day every day, because you don't want to sell your culls as pet stock for a pittance, and your feed bill is stupid, and eating 1000 chickens a year is the only way to recoup any losses
