Why do you think movie 1, 5, and 8 are canon? There was some fight between Gohan and Garlic Jr. in the canon due to that filler arc, but Krillin and Gohan meet for the first time in both movie 1 and episode 1 of Dragon Ball Z. Movie 5 is not canon whatsoever. There is no possible area in the timeline where it would fit, because Goku killed Frieza, is on Earth, doesn't know SSJ, and Vegeta is not there. 8 is not canon because Goku and Gohan aren't SSJ in some parts.
