With Alexander the Great it's hard to say due to lack of information, which is caused by the bad record keeping in those days combined with the fact that the west considers him a hero. However, estimates go from anywhere between 100,000 and several millions. A realistic number is hard to determine but I'd say 300,000-400,000 is most likely accurate. As for Genghis Khan, his horde has killed 10,150,000 people in the Khwarezmid Empire alone, reducing the former Empire's population by 90%. Meanwhile, the population of China plummeted by 40 million during his rule. If we exclude deaths he can't be held accountable for, we'll end up at about 27 million. The remaining conquests probably killed a few hundred thousand too. If we add up the numbers, Genghis Khan ends up at about 38.5 million, earning him the title 'worst mass murderer' with an advantage of millions of people killed in front of #2, which would be Timur with 17 million.

It is estimated that genghis Khan killed around 40 million. This is an estimate but that is a similar amount to Stalin and more than Hitler.

Alexander also razed the city of Tyre to the ground and built a new city in its place, and the burned and looted of the Persian city of Persepolis. There were also a number of small Bactrian cities/forts that refused to surrender, and in retaliation he killed everyone. Between civilians and military I would say somwhere between 800,000 and 1.2 million, this is just a guess though. In ancient battles, a defeated force was much more likely to be completely wiped out.

Such estimates are pretty difficult. Even for WWII there is no universal agreement over the number of dead - and that's for a relatively recent event that was extensively documented.
However, I think one can say from the record that the civilian/military ratio among Genghis Khan's victims was much higher than that of Alexander's. (To wit, Genghis Khan would raze whole cities and kill all the inhabitants - something Alexander never did, except for the one singular case of Thebes).
