Just some canon facts. Gathered from the anime, manga, Hetalia wiki and HetaFacts. Sometimes Google images.
If I remember to check the season and episode number while watching the anime, I'll add those. I also will write who is in which chapter in the titles for ease of looking up a fact when needed.
If you own a Roku, you can download a channel called Tubi and watch several seasons of Hetalia for free.

!!Please let me know it I get any information incorrect!!
