Image 4 represents prophase. It has the spindle fibres start emerge from the centrosome. The nuclear envelop breaks down and chromosomes become visible.

Image 2 represents the second stage of mitosis which is metaphase. In this stage the chromosome are lined up at metaphase as shown.

Image 3 represents the third stage which is anaphase. In this stage the  centromere split into two. Spindle fibers begin to elongate the cell.

Image 1 represents the fourth stage  telophase of mitosis. In this stage the chromosomes arrive at opposite pole and begin to decondense.
