1 or 2 he really is not a super hero like the saiyans and piccolo

None, they go Super Saiyan, and light everything up.
There are 6 Super Saiyans, Trunks, Vegeta, First Super Saiyan (Unnamed), Goku, Goten, and Gohan, without the movies, fusions, and future counterparts. Every single one would be 12, Vegeta, Trunks, Future Trunks, Goku, Gohan, Future Gohan, Goten, Gotenks, Gogeta, Broly, First Super Saiyan (Unnamed), and Vegito.
Goku can go up to Super Saiyan 4 there is no DB AF.

I would venture to say not many. Super Saiyans are from a work of fiction, Dragon Ball, and most readers/viewers understand that it is fiction. There are those that have difficulty sorting out fact from fiction such as very young children and the mentally ill. However, the majority of people enjoy saiyans for what they are, part of a good story.
If you're meaning in season 1 when he is training for the saiyans, its 88 days (im pretty sure)
there are six saiyans in all
goku went ssj 3 5,799 times
This is from the Dragon Ball series. Goku (main character) is from the nearly extinct extraterrestrial race called the Saiyans, who sent Goku to earth while he was an infant to conquer the planet but when he landed he was knocked unconscious and forgot everything.
