This is dependant on the length of the movie and the quality of the coding. I'll assume you mean feature films. Using H.264 encoding at a good quality setting will allow you to fit between 7-8 movies on average, depending on the movies length.
it depends on the movies you want to download
as many as you want

There is one way but it only works for the Kindle Fire, not the Kindle Fire HD. I have been trying for many hours to find out but sadly, no you can't.

A kindle fire HD has 40 gigabytes
Well checking the amazon page for the kindle fire, it can hold up to 6,000 books. That's 8Gb (6GB of actual space). You can also hold 80 apps, plus 10 movies or 800 songs. Hope that answers your question.
A standard Kindle has a very good refresh rate for an electronic reader, and will display books beautifully, but it can't show you video. You would have to get the upgraded Kindle Fire, which has more tablet like functionality. I am adding to this answer, I have a Kindle fire original and hdx and they both stream movies from Amazon Prime and Netflix and You Tube, there is no room or need to have the video in the Kindle memory when so many are available online as long as you have a WIFI connection avaiilable
