For the ones with the magenta hue on the underside, they could be either Trichaptum abietinum (https://www.mushroomexpert.com/trichaptum_abietinum.html) or Trichaptum biforme (https://www.mushroomexpert.com/trichaptum_biforme.html). They are practically identical looking species, but you can tell them apart based on whether they are growing on dead conifer wood (T. abietinum) or dead hardwood (T. biforme).
