They are very nice echinoderms (sea urchins), I'm sure someone on here will ID them for you.

Hi there!
I think they are the genus Echinocorys, and being preserved as flint internal moulds, will have originated in a flint nodule band within the Chalk, which means they lived between about 85 and 90 million years ago.  To be more positive about the identification, you should submit photos from different angles (particularly from beneath in this case) with a ruler as a scale.
You are not alone in finding these objects fascinating and worth collecting.  Have a look at this website: https://www.geolsoc.org.uk/Geoscientist/Archive/June-2012/Prehistoric-fossil-collectors .  This describes many instances of these being found in history and pre-history, including a 4,000 year old archaeological discovery of a grave in the Chilterns, in which the body had been surrounded by hundreds of fossil flint sea-urchins such as yours.  There is also a flint hand-axe incorporating one of these, even older.  They were often gathered by farmers who would place one on his doorstep to ward off evil, and called "Shepherd's crowns".
