I understand that these three expressions are an invitation to do something or go somewhere. I would use “давай” as in “come on” or “come with me”. “поехали” and ”пойдём” would be more like “let’s go”, but I think it’s a bit too simplistic.
In which case either of these expressions would be preferred over the other, and why?
What words must we use with each expression (e.g. must be followed by a verb or must be followed by a location)?
" Пойдём в кино?"
If you accept the invitation, next you will discuss, how to get where. It could be public transportation, taxi or someones' car. Or you would simply walk to a nearby movie theater.
"Поехали" implies using a vehicle to get where.
"Поехали в кино?"
The movie theater in question is either too far away for a walk or the person who asks that does not feel like walking.
