Limestone is chemical; though in certain cases, limestone may be organic, when it is composed of the dead remains of organisms (fossils). That's called fossiliferous limestone, or fossil-rich limestone, but regular limestone is just chemical.
Non-clastic means not formed from other rocks or rock particles.Non-clastic or chemical rock, is composed of chemical precipitate out of solution.Clastic rock is formed from particles of other rock.
Chalk is a type of sedimentary rock that is primarily composed of organic material, specifically the calcareous remains of marine microorganisms such as coccolithophores. It is not considered clastic, as it does not consist of fragments of pre-existing rock like clastic sedimentary rocks.
Coal is considered a non-clastic sedimentary rock because it forms from the compressed remains of plant material rather than from the deposition of rock fragments or grains.
Clastic rocks are sedimentary rocks consisting of bits and pieces of other rocks created by physical/mechanical weathering. Non-clastic are also sedimentary rocks; however are absent bits and pieces of other rocks and are formed through chemical processes (e.g. hydrolysis, evaporation, precipitation, oxidation) or form out of organic material (e.g. coal, chalk).
Clastic rocks are composed of broken pieces of older rocks that have been broken up by the process of weathering and are therefore sedimentary in nature. The "clasts" (bits of older rock) may vary in size.

They are all Sedimentary
Clastic sediments are sediments that have particles or pieces of rock (clasts) in them. The clasts can be of igneous, metamorphic or sedimentary rock. Non-clastic sediments are made up of dissolved minerals or organic matter.

Conglomerate is a non-folliated rock. It is a clastic sedimentary rock.

There are no metals in chalk because it is a non metal. It is also a powder
