I've never heard of aikido techniques numbered past gokyo. I just found these on the internet (I googled "aikido nanakyo," etc.) and thought they might be what the OP is looking for. I think the OP got his list off aikidofaq.
I offer no opinion as to the validity or quality of the demonstrated techniques.
First I want to thank you for the concern to find the video.
I think it is what I'm looking, I have my doubts as to whether these techniques you see in the videos are really the techniques described in Japanese.
