Typical = one that belongs to a type, one of many of the same sort.

Usual = the ones that are normally 'used' or thought of [think of the film "The Usual Suspects" - those that are often call up as possible criminals]

With the other examples, I cannot perceive a difference from 'typical'.  "Normal" could, however, refer to a mental state, which I don't think is intended here.

I'll be interested to see if other native speakers feel more subtleties.

My English teacher's words come to my mind. He didn't say anything about typical, average, normal and standard  -  probably because those words aren't difficult for Finns.

As you have said: If a person usually has the same breakfast or drink: He had his usual breakfast. He had his usual drink.

If something isn't rare: The pigeon is a common bird in England. (It's very common in Finland as well.)

If someone has no special extraordinary qualities: I'm an ordinary man. (Not very short, not very tall, not particularly intelligent, not stupid either.)

Average is close to ordinary but we can often think statistics when we use the word: The average Englishman likes tea.

 >It seems to me that usual can't be used with nouns unless the nouns are related to some verbal idea -- to something that "occurs".

That's probably true:

--

 usual describes that which happens frequently in the normal course of events and lacks any element of strangeness

<it is with the domestic artist as with artists at large -- painters, architects, and others -- the usual error lies in excess prompted by undue desire for admiration -- Herbert Spencer>

<it is usual, when visiting a new mother for the first time, to take a little present for the baby -- Agnes M. Miall>
