Your questions indicate a very basic misunderstanding of the IMAP protocol. Until that misunderstanding is clarified, you are going to have a very long and frustrating experience.

What I really want is to make sure that after log-ed in until logout, it is counted as in one connection.
It's one connection from the point that the initial TCP interchange is made (even before authenticated).
If this is true, then after login until logout there can only be one mailbox being selected (one session there).
There can only be one mailbox selected at a time. If you select mailbox2
while mailbox1 is selected, then mailbox1 is automatically unselected and mailbox2 is now selected. This forms a new session within the same connection.
"can have multiple MAILSTREAMs open, each with a separate mailbox selected", I believe you mean the mail boxes for the MAILSTREAMs might be SELECT'ed before and not closed, but only one is SELECT'ed at the moment.
No. I mean that you can have multiple connections, each with a different mailbox SELECTed. This is the only way that you can have more than one mailbox SELECTed at a time.
Also if the MAILSTREAM s1's mail box had been SELECT'ed before but now another mail box is SELECT'ed. Could we still call this MAILSTREAM s1 open until it is closed?
Any existing MAILSTREAM is not affected by opening a new MAILSTREAM. Each MAILSTREAM is completely independent of any other MAILSTREAMs.
By passing a non-null MAILSTREAM to mail_open(), you can do a new SELECT on a MAILSTREAM, without closing the connection.
Will the data downloaded into cache while it was open be still in the c-client cache, until s1 is closed even if other mail box is SELECT'ed now (i.e. can still use some of the mail_xxx() function against this stream s1, such as get msg number..)?
Each MAILSTREAM has its own cache. The cache is destroyed when the MAILSTREAM is closed, or if the MAILSTREAM is passed to mail_open() to SELECT a new mailbox.
