What's the difference in Gaia generations?

Question

What is the difference between a 4th generation item and a 2nd generation item? When all the evolutions are complete, will the name change?

Answer 1

The name will always say the generation number even after the evolution is complete. With the Pora Ice, the icon was also different (search Pora Ice in the marketplace to see), but the rest have all had the same icon.

So far, that is the only difference after evolution is complete. (Of course, later generations finish evolving weeks or months after the first generation depending on the cycle.)
