One yellow foliose, one variably grey (?)with black dots and one crustose black.

The yellow lichen could be Caloplaca flavescens which is placodioid (crustose with lobed margins).
Brownish-black one is probably a Verrucaria.
Were the rocks limestone as if so the whitish-grey one could also be a Verrucaria sp.
The rock was limestone, so I'll look into Verrucarias.
