While some of these are unquestionably used (a clowder of cats, a pack of dogs), many just surprise me. For example “a cackle of hyenas”, “a memory of elephants”... For the latter I found a confirming article, namely this one.
Edit: I realise the impracticality of going through each word in the list. That’s why I reworded to “any” almost immediately. I expected that native speakers would quickly recognise at least one construction, for instance “a cackle of hyenas”, as a hoax. Although I have been an avid reader of English prose for decades, I had no idea about the origins of venery and that it was actually meant to be funny!

They are terms of venery, which means that they are quite likely to have been made up just to be a bit funny and act as linguistic curiosandThere is another piece of circumstantial evidence: terms of venery in English are often quite transparently meant to be amusing or exaggerated gibes at perceived characteristics of the animal in question.andIt was lingual fun. The trend developed in the middle of the 15th century and one of the first such lists occurs in The Bokys of Haukyng ... better known as Boke of Seynt Albans or The Book of St. Albans printed 1486.– Mari-Lou A Feb 07 '18 at 23:28
