EiBiCi,
"Are sanstones rocks?"
Yes, sandstones are rocks.
"Are rocks made up of elements?"
Yes, ultimately all matter on earth is made up of elements.
"Are rocks and minerals igneous?"
No, not all rocks and minerals are igneous. I'll give a brief description of how things are classified that may help you think about this: Elements, of course, are the basic substances that form the building blocks for all other materials. Minerals are solid, crystalline compounds found in the earth that are formed by elements combining in certain ratios. Minerals are the substances that are sort of the "building blocks of earth materials". A solid earth material that is made up of one or more minerals that forms in a particular way is a rock. So rocks are made of minerals, and minerals are made of elements. There are 3 types of rocks that are classified by how the rock forms, and igneous rocks are one of them. They are:
Igneous: forms from the cooling of molten rock
Sedimentary: forms from the aggregation of peices of pre-existing rock
Metamorphic: forms from the application of heat and/or pressure to pre-existing rock.
So some rocks are igneous, but others are not. Minerals are not really considered "igneous", "sedimentary", or "metamorphic", only rocks are. There are certainly minerals that are commonly found in a particular rock type, but in fact some minerals can be found in rocks of all three types.

Are sandstones rocks? Yes, they are sedimentary rocks. Are rocks made up of elements? Technically, yes. However, rocks are made up of two or more minerals and minerals are made up of one or more elements. Are rocks and minerals igneous? Igneous rocks are igneous. All other rocks are not igneous. Minerals are another thing. Many minerals are both igneous and metamorphic, (example, quartz) or igneous and sedimentary (example, apatite).

Sandstones are rocks, rocks are made up of elements and compounds as in minerals. Rocks and minerals are both igneous and non-igneous (as in sandstone or limestone which are sedimentary i.e. formed by sedimentation on river and sea beds).
