Mostly Caloplaca

Sure, you’re right, there are a few species here, but the orange dominates and is the only one we can really id:

orange thick one covering most of the photo – Caloplaca trachyphylla; very common in desert southwest; note the characteristic radiating, convex, rough lobes around the margin

paler yellow stuff here and there – may be distinct; maybe Candelariella; looks like it lacks marginal lobes, all sort of uniform lumpy yellow

thin dark brown stuff all over – probably impossible to id from this photo

whitish-bluish rosettes – again, hard to id; possibly Xanthoparmelia (the bluish color could be an artifact of the intense light?) or a Physcia or even Lecanora (although it looks lobate like a foliose species, but too flat for the lobate Lecanora species like L. lecidea or L. garovaglii)
