The types of multiplicities connected with association relationship are:

1. One to One: This is when one instance of a class is associated with one instance of another class. For example, one person is married to one person.

2. One to Many: This is when one instance of a class can be associated with many instances of another class. For example, one mother can have many children.

3. Many to Many: This is when many instances of a class can be associated with many instances of another class. For example, a student can be enrolled in many courses, and a course can have many students.

The "Two to one" and "One to Two" are not standard multiplicities in association relationships. However, they could potentially be used in specific contexts where it makes sense to limit the association to exactly two instances.
