8th grader petri dishes - seeking help to identify colonies

I did a study of hand washing and hand sanitizer. Is anyone on the list willing to help me identify what grew from my unwashed and even washed hands? I attach three photos representing the yellow, white and orange growths found after several days on agar plates. Thank you so much in advance.
