1 and 2 mean the same thing.
3 and 3-1 are pretty close in meaning.
4 is very close; it means it took no longer than a week to finish the project.
"In" can also mean no longer than a particular period of time:
1. Can you finish the job in two weeks?
2. Can you finish the job within two weeks?
--------------------------------
The definition is from a dictionary. In this case are both the same?
3. We finished the whole project in a week.
4. We finished the whole project within a week.
-----------------------
Does #3 mean the following?
3-1. It took a week for us to finish the project.
Or does #3 mean #4?
