Mozart died in 1791, so Haydn would have been 59 at the time.
Haydn was older than Mozart by 24 years.
Mozart's influences were Bach's son and Franz Haydn. Haydn was more of an influence to him. Mozart dedicated a set of six sting quartets to Haydn.
Haydn
Beethoven and Haydn certainly did, Haydn taught Beethoven. Between Beethoven and Mozart the picture is less certain, they may have met in Vienna in 1787, and some people think that Beethoven may even have had a few lessons from Mozart. However the records are not clear or contemporaneous. Mozart and Hayden were great friends.

Haydn and Mozart

I think that Mozart and Haydn are quite alike but Haydn said that in 100 years there will never be another as great as Mozart !
Mozart is one of the firsts Classicists(From Haydn-Beethoven).... he is from the age of Enlightenment.
Mozart, then Haydn and Beethoven being slightly more romantic I would put him down last or not at all
