Ok. Holy hand Grenade, Super Sheep, and Old Woman (granny bomb) had been a Worms Standard. Those 3 in particular have traditionally been *special* weapons which only came from Crate drops and weren't in the traditional set inventory. They might still be in there.
Those 3 were well engraved in Worms since Worms AGA Director's Cut. A version that still predates most of the PC ones. Mad Cow was introduces in Director's Cut, but I don't think it made it into any others. The cool thing about MAD COW was that it had a secret. It either fired 3 running jumping cows in one direction, but if you released it in Mid Air, during the straight-up jump; it fired cows in both directions from the worm. Of course, not all the time would you use the jumping version as it can lead to friendly fire.
Still, the ones shown are the main weapons that matter for good worms gameplay; the others are gravy, though they are good gravy. The shown weapons here are the traditional weapon-set. However, in the very old-school style; the Bananna bomb, Jet Pack and Teleport, were often configured to be acquired by Crate Drop only. Sometimes, people elected to set things up so teams started with a couple of Jetpack uses.
