fair 1 faf = 27, fair 2 = 32, nair = 33, bair and uair = 30. Next fastest hitbox is either Witch Twist at f4 or fair 2/3 which is listed to have a hitbox on f7/12. Not sure how that works since for example, Ike's jab 2 is listed as coming out f3 but it takes longer to get to since you have to go through jab1.
uair faf = 26. Uair is also the fastest aerial to get out again at f6
Same as Jr. with uair faf = 34 and uair coming out f6
bair faf = 31 and uair comes out f4
Special case with DK. Bair faf = 32 with next fastest hitbox being f4 Spinning Kong but that puts you in helpless. After that, it's f6 uair
