I'm not great at ID'ing from photos. But the larger tan/red rock with the black fern like pattern are known as dendrites and are not fossils but usually manganese or other mineral deposits that branch out as they are layed down.

they are sampled in a sulphides mines areas ? lead-silver or zinc mines ?
or you took inside a cave ?

the dendrites are typical of dolomite or limestone
