The only one of them that I know is the last one. It's name is Deavorick, it is one of the new kaiju introduced in the Ultraman Orb Movie.
Thanks, I've figured out who the top two are, but the third guy, still not sure.
I found well searching ultraman figures and saw that guy as one of the figures on sale. I didn't know who he was, but he was listed as an ultra kaiju.
The third one is Cotton-Poppe from Ultraman Zearth.
1st: Metallinome from Captain Ultra
2nd: Neo Geomos from Ultraman Dyna
