Two bus stops: which noun becomes plural?
You are describing your neighborhood: two places where buses stop and three shops that sell books. The useful phrases are two bus stops and three bookshops.
Professor Scott MendozaThe short answer
In bus stop, stop names the thing and bus tells you its type. For more than one, write bus stops. The same small pattern gives coffee cups and bookshops. Do not add a plural ending to every noun you see.
Find the main noun—the thing you are counting.
A compound noun combines words to name one idea. In these examples, the last part is the main noun: stop, cup or shop. That part becomes plural. Bus, coffee and book identify the type and keep their form in these compounds.
Count the stop, cup or shop
one bus stop → two bus stops
one coffee cup → four coffee cups
one bookshop → three bookshops
A bus stop can serve several buses. The singular form bus inside bus stop does not tell you how many buses use it.

A little more clarity
Common questions
A few useful details before you move on.
Does a compound noun always have a space?
No. Bus stop has a space; bookshop is one word. Other compounds use hyphens. Learn the usual spelling of the whole expression rather than applying one spacing rule.
We found a bookshop near the bus stop.
Does bus stop mean only one bus stops there?
No. Bus identifies the kind of stop. It does not count the vehicles using it. A stop can serve more than one bus.
Several buses use this bus stop.
Take it into your day
In bus stops, coffee cups and bookshops, the last part carries the plural. Keep the type word as it is.
