Fatal whale attacks on humans are extremely rare, with only a few documented incidents in history. Most interactions between whales and humans are non-aggressive, as whales generally do not pose a threat to people. The few reported fatalities often involve close encounters with large species, such as orcas or humpback whales, but these occurrences are exceptional. Overall, the number of deaths attributed to whale attacks is very low, likely fewer than ten.

I know that a killer whale has killed a GIRL in Florida, when she didn't have her hair tied back and it thought she was a seal, so she was grabbed by her hair and pulled underwater, and drowned. On December 24th 2009 a man got attacked by a killer whale and died. I don't know if any other men have died as a cause of killer whale incidents, but you can look it up on the wikipedia page: Killer whale attacks on humans.
On September 11, 2001, a total of 184 people died at the Pentagon as a result of the terrorist attacks.
Lots.

It depends on what year. For example, there have been 1,159 reported crocodile attacks on humans since 2010, and many other attacks go unreported.
2,606 people died in the Twin Towers, not including the people on board the two planes that crashed into the towers
