No. The term "cattle" is a general collective noun referring to a more than one bovine, be it a cow, bull, heifer, steer or calf or any or all of the above.
You add an apostrophe to the "s" like so: 's to make the word as "cattle's."
"of a herd of cattle led by ranchers" as you have used it above is already the possessive for of "a herd of cattle led by ranchers"! For example: The herd of cattle which was led by the ranchers bought a farm. The farm is now owned by the herd. It is the herd's farm. It is the farm of the herd of cattle led by ranchers.
Cattle is a plural noun, referring to more than one. There is no particular word for a single bovine animal.If you wanted to refer to one animal and still use the term cattle you could say one head of cattle, but even head has a connotation of more than one. The usual method is just to call the animal by its name: cow, bull, bullock, steer, heifer, calf, or so forth.
No, "him" is not a possessive pronoun. It is an objective pronoun used as the object of a verb or preposition. Possessive pronouns include "his" as a possessive form of "he."
"He" can function as a possessive pronoun (e.g., "This is his book"), but it is not a possessive noun on its own.
