    The center would be in the dark area in the middle of the galaxy, Right Ascension: 53.2082769 ° Declination: -27.9015134 °

    So 1 and 2 would be the blue and red galaxy, with a redshift of 0.9, so 7.34 billion light-years away.

    3 and 4 would be distant green galaxies at 4.7, so 12.4 billion light-years away, or 9/10 to the edge of our observable universe.

    5 must be another green one

    6 is the spiral just off the image on the right, "only" 2.84 billion light-years away. The galaxy is closer to us than to the other galaxies.
