The first is a genuine container for ink blocks or wax, likely the date is right at 18thc Yung Cheng or Yong Zheng, depending on Mandarin etc or not, the red seal mark is an expert seal from China, so it is likely genuine.
The other 2 are broken fragments of, for the larger one a large baluster vase or something similar where the part of the broken original item has been cut and ground to make the lid of the silver alloy box, same again for the smaller one, it was common practice in later 19thc into the 20ths and sort of recycling of Ming and Qing antique porcelain that had been damaged.
In the Ming dynasty sherds of ceramic from the famous wares known as Chai ware in sky blue glaze with delicate crabs claw crackle markings were used in the imperial soldiers and officials cap - hat badges set into silver, they were excavated pieces of the most famous tang dynasty ceramic known to the Chinese as '' Chai yao '' chai kiln ware, the ware was often found in burials and tombs and re used for such things as cap hat badges because the actual kiln was never found and was apparently destroyed during the tang dynasty wars.
You can pretty much say that the Chinese have been recycling for a lot longer than us western white devils have.
All in all, probably worth a tad more than $75
I've improved the seal photo a bit so you can see the details easier.
