It depends on what area you're in.
A "50-year flood" refers to a flood event that has a 2% chance of occurring in any given year. This statistical measure is used in flood risk assessment and planning, indicating that while such an event might occur once every 50 years on average, it can happen more frequently or not at all in that time frame. It's important for understanding flood risks in specific areas, but it does not guarantee that a flood will happen once every 50 years.
A 100-year flood is a flood of a given size for a particular area that has a 1% chance of happening in any given year. On average such an event will happen once per century. Remember, though, that this is merely an average; it is entirely possible for two 100-year floods to happen within a year of each other or for none to happen for thousands of years.
Tornadoes can happen at any time of year but they are most common in sprind and early summer.

Tornadoes can occur any time of year but it is most likely to happen during a thundery and harsh spring.
No. Contrary to popular belief a 100 year flood does not occur once a century. The term means that there is a 1% or one in a hundred chance of such a flood occurring in any given year. It's quite possible to have two 100 year floods in a row.
Yes. The "100 year" only refers to the mathematical chances, not to the actuality. Just as the 'chances' of tossing four heads in a row with one coin are 1 in 16, it doesn't mean that it won't happen twice in a row some time.
between June and September
Tornadoes can happen at any time of year, but they are most common in spring and, to a lesser extent, early summer.
No. A 100-year flood is larger than a 50-year flood for any given area.
Yes, a 100-year flood is more catastrophic than a 50-year flood. The term "100-year flood" refers to a flood event that has a 1% chance of occurring in any given year, while a "50-year flood" has a 2% chance of occurring in any given year. Therefore, a 100-year flood is rarer and typically results in more severe consequences in terms of damage and impact than a 50-year flood.
