Yes. Non metals are certainly considered to be matter.
Everything that you touch is MATTER. You are matter. So solids, liquids and gases are matter. It follows that non-metals are matter. NB THere are only two liquid elements in the periodic table, they are bromine and mercury.
Nonmetals are a type of element, not a state of matter. Nonmetals can exist in different states of matter at room temperature, depending on the specific element. For example, oxygen is a nonmetal that exists as a gas at room temperature, while sulfur is a nonmetal that exists as a solid.
nonmetals
Nonmetals typically exist in the solid or gaseous state. At room temperature and pressure, nonmetals such as carbon, sulfur, and bromine can be found as solids, liquids, or gases depending on their specific properties.

Examples: metals or nonmetals, radioactive or not radioactive, classification after the state of matter, reactive or not reactive etc.
nonmetals look like metals but are dull and brittle .
Not necessarily. Nonmetals can exist in different states of matter at room temperature, including solid, liquid, or gas, depending on their specific properties. Examples of nonmetals that are solid at room temperature include sulfur and carbon in the form of graphite.
The nonmetals consist of Boron (B), Silicon (Si), Germanium (Ge), Arsenic (As), Antimony (Sb) and Tellurium (Te). At 25 degrees Celsius (room temp) all of these are in a solid state. It is important to remember though, that gases can also be considered non metals, though because, obviously, they are not metals.
Nonmetals are not malleable.
Some are solid (eg carbon) some are gaseous (eg oxygen) and one is liquid (bromine).
The nonmetals share the atoms when reacting with each other.
