In most cases yes. Portions of slow moving rivers, or where sediments that were carried in currents came to a rest, intact fossils can be cemented among the stones.

sedimentry
Sedimentary rocks, such as limestone, sandstone, and shale, are the most common types of rocks that contain fossils. Fossils are formed when the remains of plants and animals are buried in sediment and eventually become preserved in rock over time. Igneous and metamorphic rocks typically do not contain fossils.

Firstly you must know that a conglomerate is a sedimentary rock. Only a sedimentary rock could have shells in it, and only limestone. Other rocks contain fossils like shells but only limestone can form them as the impression is filled by calcite, which collectively forms limestone.
Shale and sandstone are fine-grained sedimentary rocks that compact well to preserve fossils due to their low porosity and permeability. Conglomerate, being a coarse-grained rock with larger particles and higher porosity, tends to have more spaces for organic material to decompose or be destroyed before preservation can occur.

yes
Fossils are the mineralised remains of organisms and contain no organic material.
Metamorphic rocks do not typically contain fossils, as the intense heat and pressure involved in their formation often destroy any remnants of organic matter. Igneous rocks are formed from molten material and do not contain fossils. Sedimentary rocks, which form from the accumulation and compression of sediments, are the type of rock that commonly contain fossils.
