Active Directory 101 - OU, Branches, Containers

I need some quick help differentiating between a few key concepts within Active Directory.

1) Is a branch essentially the last OU in the hierarchy?  For example, let's say we have an OU called "Office", then a child OU called "North East", then a child OU of North East called "Boston" - WOULD this be considered a branch?

2) What about the difference between an "OU" and a "Container"...is there one, or are they two of the same?

3)  Can a user (or printer or other resource) belong to MORE THAN ONE OU (I'm guessing the answer is "No" - but would like an expert explanation of this)

Concise and succinct answers would be appreciated.

One additional question...if I search and locate a user within Active Directory Users and Computers, how can I quickly find out what OU they belong to?
Also (promise this is my last suffix to this question) can you tell me why I can't add a sub-folder to the default 'Users' folder within ADUC?  In our PROD environment, we have multiple folders under USERS (which is the out of the box folder - Not an OU from my understanding) - but when I try to create sub "folders" in another test environment, I can't....any suggestions?

Thanks for the quick response.

Regarding answer one, I'm not so interested in permissions or delegation - I'm really trying to find out whether my understanding of the terminology is correct.  Using the example I provided initially, would it be correct to call the Office > North East > Boston a "AD Branch"?

Regarding answer two, please view this additional question (https://www.experts-exchange.com/questions/23916461/Active-Directory-Users-Container-vs-Organizational-Unit.html) I've posted where you can see that sub-containers can be created....now I just need to find out how.

Regarding answer three - that's what i thought, but needed to hear it from someone else.  With thanks mboppe!

Thanks Rob.  

I think I'm now clear about what a branch is..."any OU container which contains sub-OUs" - or at least the way I look at it anyway.

One thing I've not been able to do from your answer to question 4 - is see the OBJECT tab (see image below).  This is in my test environment WITHOUT MS Exchange Installed.  Can I assume this is the reason I cannot see it?

Regarding your answer to question 5, we have a whole sub-container structure under 'Users' which is apparently a legacy from when we moved from Exchange 2000 to Exchange 2003.
