What does each one mean and age?

Hi, might be silver, but I’m not sure and I’m struggling to identify these hallmarks. There might be an 800 to the south east of the crown? Any help would be massively appreciated!

I got this box from etsy.
Hallmarked HBROS
Any information here?

Maker mark?

hello! i work in a jewlery store and ive been searching for this stamp meanings but have no luck... anyone got ideas?

Looks like a Spanish post 1934 star but can’t make out the maker hallmark at all on this crystal decanter. Any help appreciated !

Found this in my grandparents’ old silverware and is the only one that does not have a manufacturer stamped (from what I can tell!) Any help would be appreciated!
