Looking at these pictures again I realize that the scans in the first two rows are from a doujinshi called 'Dolls'. I actually have that one so I'm surprised I didn't recognize it at first. The characters in said doujinshi are Ooc but nevertheless it is still a beautiful, touching story with gorgeous art.
I have the link to the site where I got it from if you'd like it, let me now. You'll need WinRAR to download it though, just google and download it (WinRAR that is) if you don't already have it. They have lots of others there too so maybe they'll have the doujinshi where the other scans come from, I dunno, I'll check it out because I'm particularly interested in the GinxKira one myself.
Do you remember the names of the doujinshi where these scans came from? If not, then that's cool as I can probably (Hopefully) find them myself. Thanks for sharing! ^_^

The only one I remember is the Ichigo/Ishida/Isshin ones (Family something... -_-||| )and my apologies for the late reply, I was hoping my computers hard drive would be saved by now *sigh*
