The non-Goji figures on 42 are various toys of Kanegon and Booska (one of them is Booska's brother, the name of which I forget). Page 43 includes the Daigoro vs. Goliath set by Atelier G-1 that Legion just purchased, the Spectreman mentioned recently on SciFi Japan, what I'm guessing is a Mirrorman villain? (the gold one on the upper left corner), a Tachikoma, Ultraman Ace, two kaiju I don't know (below Spectreman) and the rest look to be urban vinyl stuff, or at least nothing I could remotely recognize.
Page 44's got a nice variety of characters. From left to right:
-totally unsure, Bemular, Muruchi
-not sure, Varan, Nova
-Mirrorman villain (?), no idea, Mephiras Seijin, Garamon
-Hedorah, Booska, Garamon, Gomess
-Dorako... you know the rest
Jirass is not pictured anywhere in the scans. That's Gomess, the more heavily modified kaiju made from a Godzilla suit, that appeared in Ultra Q. Jirass was only a Godzilla with a frill, and appeared in Ultraman.
