Any idea what the brown one is? and the white one? I think the orange is probably Caloplaca and the chartreuse is Pleopsidium.

Yellow one is still Acarospora, by the way

The most likely candidate looks to be Acarospora socialis. It’s the fact that it is “subsquamulose”, with the lobes thick and elevating from the substrate. There aren’t many that do that, and this (socialis) is the one that’s fairly common and widespread.

Brown is Umbilicaria for sure

Playing the odds, it is almost certainly U. phaea, the dominant species in the desert.

As for the other “incidentals”:

orange: Caloplaca trachyphylla, I agree (also a dominant desert species)
yellow: Acarospora contigua group (see comments in _observation 59918)
white: Rhizoplaca melanophthalma (also could expect R. chrysophthalma with orange apothecia_)
