Changing two or more data points in one cell using Autofill

I am new here as well as with the MS excel. How can I use the auto-fill function for changing the different values in ONE CELL.

For example, the data is

Vintage 80th birthday shirt - September 1940 Shirt - 80 Years Old Birthday Gift
Vintage 79th birthday shirt - September 1941 Shirt - 79 Years Old Birthday Gift
Vintage 78th birthday shirt - September 1942 Shirt - 78 Years Old Birthday Gift
Vintage 77th birthday shirt - September 1943 Shirt - 77 Years Old Birthday Gift
Vintage 76th birthday shirt - September 1940 Shirt - 76 Years Old Birthday Gift

I want to automatically change the 80th, 1940 and 80. Hope you guys understand and help me save hours of work on a daily basis.
I have uploaded an image also for your reference. I tried but it's not working. I saw many videos but no one talks about that. I may be missing something. Hope you guide me.
