Program is a bunch of code with some conditions. That conditions makes abnormal flow. such as stack full(Example infinite loop ->for(){} ) or not possible conditions( Example data type conversion problem like int to string).

A comprehensive list of standard exceptions can be found under the heading Inheritance Hierarchy on the below page:
http://msdn.microsoft.com/en-us/library/system.exception%28v=vs.110%29.aspx

You can also define your own exceptions, so basically the number of different 'types' is unlimited.

Exception is a runtime error or event which disturbs the desired flow of program. 
Any such error or event at runtime if not handled in code is thrown as exception. 
Few exception that i have come across are
NullReferenceException
InvalidOperationException
ArgumentNullException
IndexOutofRangeException
ArgumentException
ExternalException.
