N°1= I think the video is like a Priemer NIKKYO or SANKKYO
N°2= The second, as you well say is like a KOKYU HO or NANAMEKOKYU, not a : kote-ori-kakae-kimi, kuji-dori = Nikyo in which his elbow is in your armpit and his hand is pulled forward; Pinning their hand with your foot
N°3= The third is like a IKKYO and then projected, not a : Inverted nanakyo
