Not sure about ateroids. If you means asteroids, the Minor Planets Centre, the organisation responsible for collecting observational data for such objects, there was enough information for over 600,000 asteroids for them to have a formal designation - a number.

Which asteroids and comets are on Mercury?

how many total asteroids are there (asteroid belt AND kuiper belt) (also including rogue asteroids that arent in those asteroid belts)?

The total number of asteroids in the solar system is not known with certainty, as many asteroids are small and difficult to detect, and new asteroids are constantly being discovered. However, astronomers estimate that there are millions of asteroids in the asteroid belt between Mars and Jupiter, and potentially trillions of objects in the Kuiper Belt beyond Neptune. In addition, there are also a number of asteroids that do not reside in either the asteroid belt or Kuiper Belt, but instead follow their own unique orbits. These objects are sometimes referred to as "rogue asteroids," and their exact number is not known. Overall, while the exact number of asteroids in the solar system is uncertain, it is clear that there are many millions, if not trillions, of these small rocky bodies orbiting the sun.
