If you're looking for some rules about how this must work, you won't
find them - all these things are optional and dynamic.
Multiple accesses between two ASes at a single physical location is
possible, yes. It's probably a good idea in most cases - whether it
happens or not is usually a matter of whether the cost (both capital
and opex) is worth it, I imagine.
RE. your original question (2) - yes a single router in each AS and a
link between them is the simplest. Add more routers and more links as
required to meet capacity and resiliency requirements, where cost
permits.
