If you want some good information that is already recorded, I would go with last year's event stats to help yourself out
Just to sum it up, Raonic had the most aces at 94 and he played 4 matches. Underneath him were Roddick and Isner who played 4 and 3 matches respectively but they only had around 75 aces.
As far as Djokovic, Berdych and Lopez, Lopez is by far the most productive in that group. According to last year's stats, he had 37 aces and he only played 2 matches. Berdych on the other hand had 38 aces which came from 5 matches while Djokovic had 51 aces in 7 matches. So as alter ego pointed out, while Lopez will rack up the most in one match, he may be poor to choose for an entire tournament as he doesn't normally get into the 2nd week. Similarly, Karlovic served 48 aces in his only match, albeit a five set match against Dodig.
As far as Tsonga, he didn't play a great Australian Open last year, and only gathered a total of 37 aces in his 3 matches even though 2 of his matches went to 5.
But yeah, I think last year's statistics will be the perfect indicator as virtually all those players except for Lopez and Berdych have been on the up while those two are pretty questionable.
Raonic will get the most aces in the tournament
Karlovic will be the most aces in a match
Djokovic will get the most aces out of those 3 players
Tsonga will not be in the top 5 of the ace count at the end
