I have babysat for my 5-year-old brother while my parents weren't home or at the story. I also have babysat my friend 2-year-old daughter while she was gone at late nights from 2-6 hours which involves diaper changing. I also have babysat a 7-year-old girl where I took her on walks to the park but I always ask there parents before I go anywhere with there child. I can cook basic food as well. I don't have much experience with multiple kids at a time, but once I babysat a 2-year-old, a 4-year-old, a 6-year-old, and a 7-year-old at one time.
