This is mid 18th century creamware made in Staffordshire, England.
This is called Whieldon pottery, made ca 1755-1770's. Both the creamware piece and this are very light weight. From what I can see from your pics you may have a piece of this.
The is German Westerwald pottery. It is still being made and has been made for several hundred years. Get us close ups and I can probably date it to within 50 years.
This is 18th century slipware. I think you got a good chunk of it from your previous post.
