I don't think any of them are surprised, none of them even look that surprised. I think they were all just waiting for him to inevitably arrive. To me at least, they all looked like they were doing a "They're here" face.

As for Oshō, I just think he got that pose because he's the de facto leader. Also, considering his special ability, wouldn't (or shouldn't) he know Yhwach's real name ? Whether that means anything or not, I dunno.
