I understand that you would like to know the last 5 processors in chronological order. If that is the case then I would like you to please take a look in the following link:
Processors in chronological order
That link has a list of the different processors released in the last quarter of 2017. You can also change the settings of the "search" in order to get more accurate results.
If what you are asking for is the chronological order for the last five generations of Intel Core processors, the summary can be obtained from this WIKIPEDIA page: List of Intel microprocessors - Wikipedia.
