It varies - from a few centuries to a few billion years.
But its not a meteor until it hits an atmosphere (a matter of a few seconds to minutes).
The average growth rate is 0.13 mm a year
No, a single meteor would not be able to take over the whole state of Florida. Meteors are space rocks that burn up in the atmosphere or impact the Earth's surface in a localized area. The size of a meteor would not be large enough to cover an entire state like Florida.
Stalactites typically grow at a rate of 0.01 to 0.02 inches per year. It can take hundreds to thousands of years for a stalactite to grow to a noticeable size, with some of the largest ones taking tens of thousands of years to form.

It can take thousands of years for a stalactite to form. The rate of growth depends on factors such as mineral content in the water, temperature, and air flow in the cave.
Probably a few million years. Most likely many years, due to Evolution. :P
Many Years. Many Years.
1 million years
1 million+ Years to be a diamonds... :/
1.
One Billion!
it takes a delta to form 100 years or more
It depends on the meteor.
There are many types of fossilization. Some take a surprisingly few number of years, and others occur over periods of millions of years.
Many such meteor showers repeat regularly every year, so you can look it up in relevant references. For example, the Wikipedia article "List of meteor showers" lists several.
It could take minutes or thousands of years, depending on the rate of cooling.
