Can you specify in more detail what exactly you are looking for?

The same rule does not govern all of the pairs you mention. But there are indeed differences between them. See the following examples.

Can & Could

I can climb a tree. -- I am able to do so. (ability)

I could climb a tree. -- I might feel like doing so. (possibility)

Shall & Should
I shall climb a tree. -- I plan to do so. (expectation)

I should climb a tree. -- I ought to do so. (obligation)

Will & Would
I will climb a tree. -- I am determined to do so (determination, command, etc.)

I would climb a tree. -- I would if I had a reason to do so. (possibility)

May & Might (often used the same)

I may climb a tree. -- (Mother has told me) I am allowed to do so. (permission)

Or: I am thinking about doing so. (possibility)

I might climb a tree. -- I am thinking about doing so. (possibility)

Normally, the pairs that are put together are "will" and "shall" or "can" and "may." But that is a different and more complex discussion.
