I have the ATL Metamodel (attached file). I want to know Is there any document to explain this metamodel in more detail?

The closest documentation is this: https://wiki.eclipse.org/ATL/User_Guide_-_The_ATL_Language

To learn more about how ATL text maps to the metamodel, you can inject your transformations into XMI models (requires ATL/EMFTVM to be installed):

Right-click an ATL file, and select Open With -> Other...
Select Sample Reflective Ecore Model Editor
Select from the main menu File -> Save As...
Choose a folder and file name ending in .xmi

In the ATL metamodel, we have "oclType" class with "name" attribute. I want to know what save into this attribute?

It's the name of your class in your model if his type is OclModelElement, otherwise it's look like to have no value.
For example, if you have something like o: MM!Class(), you will have an OclType element with name="Class"

You can easily explore your ATL model with a model browser like "MoDisco Model Browser" (right clic on your atl file (no need to generate a xmi version) -> open with -> choose your viewer).
I hope this will help further investigations.

In the ATL metamodel, we have "VariableExp" class with "name" attribute and "referredVariable" references to "VariableDeclaration" class with "varName" attribute. Can any one explain what are these elements?

I have also another questions, "oclExpression" contains all Expressions or just Expressions using ocl?
Is "Binding" Assignment Statement?
What is the difference between "BindingStat" and "Binding" classes?
Would you please make an example of "propertyName", attribute of "Binding" class?

Sorry for a lot of questions.
Many thanks for your time
