When is a hurricane considered a tropical storm and what are all the different types a storm a hurricane can turn into?

A hurricane cannot be a tropical storm as by definition a tropical storm is weaker than a hurricane. A tropical storm is a tropical cyclone with winds of 39-73 mph. Only when winds reach 74 mph or greater is the storm considered a hurricane. A hurricane can weaken into a tropical storm and from there into a tropical depression (winds under 39 mph). A tropical storm or depression may also degenerate into a remnant low, which is too disorganized to be considered a tropical cyclone. A tropical cyclone (hurricane, tropical storm, or tropical depression) may also become an extratropical cyclone after moving over land or cold water. Around the world hurricanes have different names. In the northwest Pacific ocean they are called typhoons, In the Indian ocean they are called intense tropical cyclones, and in the south Pacific they are simply called cyclones. However, these are just different names for essentially the same kind of storm.
