Who witnessed the crucifixion?

1. As, the question asks, can anyone aggregate for me and put a small list of who all witnessed the crucifixion of Jesus Christ, in the decreasing order of the person's importance (popularity). e.g. First the disciples and then other notable people who witnessed the event in that order. A list of roughly 25 or less number of people would suffice. 2. Also a related question, who exactly witnessed Jesus Christ saying these words at the time of his death, "Father forgive them?". (Please support the answer to this line with **authentic** references)
