They all clastic with medium grains sizes. They are cemented by Silica, carbonates, and clay. They form from sediments that were transported either by water or wind. Gravity had a part in it too. Do you know any differences? Do you know anymore sandstone sedimentary rocks?

A ferruginous sandstone is mainly cemented together by iron oxides.
A glauconitic sandstone contains the green mineral glauconite.
Flagstone sandstone is a non scientific name referring to sandstone slabs which are used for building/roofing etc.
Some other common types of sandstones are:
Arkose Sandstone (or Feldspathic Sandstone) - sandstone where a lot of the sand grains are feldspar (> 25%). Feldspar breaks downs to clays quicker than quartz does.
Quartz Arenite (or Quartz Sandstone) - sand grains are nearly all quartz.
Lithic Sandstone (or Greywacke) - a lot of sand grains are fragments of rock, rather than whole crystals.
You can also add prefix's like:
Siliceous - cemented together mainly by silica
Coarse - sand grains are mainly on the large size for sand
Fine - sand grains are mainly on the small size for sand
Poorly-sorted - grains are of very different sizes
Well-sorted - sand grains are of similar sizes

Glauconitic sandstone is a greenish sandstone with many grains of glauconite.
Ferruginous sandstone has iron rich (iron oxide) grains and/or cement.
Flagstone is a landscaping term: used for sandstone or other evenly layered sedimentary rocks that split into flat layers useful for making walkways, pavers, rock walls, etc.
