Gneiss metamorphosed from shale, sandstone, granite and conglomerate.

Neither. Gneiss is a foliated metamorphic rock whose immediate rock ancestor was either schist or a form of granite. Limestone and sandstone are both sedimentary rocks.
If broken down it turns into sandstone. If morphed it turns into gneiss.
Granite, Gneiss and then the sedimentary rocks like Sandstone and Limestone.
Granite, diorite, gabbro, basalt, sandstone, shale, gneiss.
Granite, gneiss, sandstone, and schist. Possibly more than that.
Gneiss turns into granite. Though it comes from shale."GNEISS can turn to migmatite and then totally recrystallize into granite."
They are both metamorphic rocks. One difference is the rocks they are formed from. Gneiss is formed from Feldspar and Quartz. Gneiss can also contain muscovite, biotite and hornblende. Quartzite is formed from sandstone. Also Gneiss is more intensely foliated than Quartzite. This can be seen in the bands formed in Gneiss, while quartzite has no bands. Pure quartzite is white, while Gneiss is grey or pink, with dark streaks.
Sandstone can metamorphose into quartzite.
No, certainly limestone could not occur as a lunar material as they are biological products. The others too are a result of terrestrial geological processes - sandstone, slate, gneiss - that have not occurred on the moon. However it is possible that the minerals talc (unlikely) and quarts (very likley) would be present in lunar rocks.
