No but ChiChi did have Goten who looked exactly like Goku during the Great Saiyaman Saga-Kid Buu Saga. However, there was a Goku Jr on the final DBGT movie who was Pan's (Gohan and Videl's daughter) grandson. We don't know who his mom or dad are but we do know that he looks exactly like Goku and is the great-great-grandson of the original Goku. But, no, ChiChi never had a Goku Jr.
Gohan doesn't train Videl in DBGT.
Videl in the anime seem as the same age as Gohan but because Gohan went in to the Hoibolic Time Chamber, he is likely younger than Videl
They meet the first episode Videl appears. They even end up having a child by the end of the series.
Great Saiyaman of course because Gohan is stronger than Videl...
Gohan teaches her during The Great Saiyaman Saga.
In the anime:Videl finds out when she sees the great saiyaman get a cut from a dinosaur and then sees a cut on the exact spot as Gohan. She puts two and two together and blackmails him by saying that she will keep his secret if he competes in the world martial arts tournament and if he teachers her how to fly.
Play as him.
