In the first two pictures it is hard to see detail, it looks like it could be a mite or some other kind of arachnid. Is it possible for you to count the number of pairs of legs? The third picture could be a fungus gnat adult. It would be easier to identify if we could see the pattern of veins on the wings, which may be hard for you to do depending on your camera. In the last picture the hairs on the root could be normal root hairs. See these images for examples:
