Attack! The Ultra-Family! (Ultraseven, Ultraman Jack, Leo, and 80 showcase)

An old tape that showcases Ultraseven, Ultraman Jack (as known as Kaettekita Urutoraman, the Return of Ultraman), Ultraman Leo & Astrar, and Ultraman 80 along with Julian, and a bunch of monsters they fought against. I also keep the old commercial pieces.
This is what introduce me to the Ultraman franchise. Never knew what was going on in this tape before :P
I see no information about this tape anywhere on the website, and I do not know Japanese, so I'll be needing your help on trying to piece together what's going on. I want to add subtitles to this video, so if you guys can translate the stuff for me, comment below. I'll credit you guys. Also, let me know what are the name of the songs that are being played.
I don't own any of these materials by the way.
