There are the last 4 chips I need help to ID.

Basic Info is really all I am looking for like what do we call them, does anyone know where they might be from, and any value.

Also I would love anyone's opinion on this .50 Riviera Chip. To me it looks like N6249 but could it be N3043. If you look at the online Guide this chip should be N3043 but if you look at the Chip Rack this chip looks just like N6249.

Thanks for the help.
