I.D. help

Fairly clueless about these guys. I need names, manufacturers, current pricing, etc...

Japanese text only on Dunbine.
"Made in Japan" on left foot on Ippatsuman (?) Japanese on Right and back.
(?) Red fig Bandai '94
(?) Blue fig "Japan" and "1983" and Japanese

Thanks!

 

1: Aura Battle Dunbine - Clover (standard size)
2: Sokkyu Gou/Ippatsuman - Takatoku
3: ?
4: Plawres Sanshiro figure part of a set of three.

 

Is the Dunbine 'Clover standard size' or the same standard size as other sofus (8~9")?

 

#3 is "Luckyman" from the Manga of the same name it ran in Shonan Jump in the 90s. The kanji on his chest means good luck.

 

Standard size sofubi. Roughly 8 inches.

 

Nice to learn Clover made vinyl. I didn't know. Thanks for assist, you guys are super!
