The sequence is as follows:
Superconductors have no resistance. Conductors have low resistance, semiconductors have intermediate resistance, and insulators have high resistance.
Superconductors have the lowest resistance of all materials, with resistance dropping to zero when they are cooled below a certain critical temperature. Conductors have lower resistance than semiconductors and insulators, which have significantly higher resistance and do not conduct electricity as effectively.
Most substances fall into two categories - conductors and insulators. Conductors are those which electricity can pass through relatively easily. Metals are the usual example, but other substances such as graphite and polar liquids such as water are also good conductors. Insulators are poor conductors: those that electricity cannot pass through easily. Most plastics are insulators. Some substances fall in between: these are semiconductors, which allow electricity through in some instances, but not in others. This property makes them very useful in electronics. Some substances can be such good conductors that, under some circumstances, they can allow electricity to pass through them with no resistance at all. These are called superconductors.
Semiconductors have resistance levels between that of conductors and insulators. They conduct electricity better than insulators but not as well as conductors, making them useful in electronic devices. Examples include silicon and germanium.
Conductor are materials that conduct electricity. There are also semiconductors, which conduct electricity but not as well, and superconductors, which conduct electricity without resistance when very cold.

Conductors have lower resistance than semiconductors and insulators, which have significantly higher resistance and do not conduct electricity as effectively.
Conductors are materials that pass electrical current easily, that is, with low resistance. Insulators are materials that do not pass electrical current easily, that is, they have high resistance. Conductors are ordinarily metals, and insulators are ordinarily nonmetals. Some examples of conductors are: Silver, Copper, Carbon, and Aluminum. Some examples of insulators are Glass, Nylon, and Wood (as well as Air and Vacuum). Conductivity is a function of the mobility of Electrons in the materials in question. Conductors have high mobility and conductors have low mobility. Semiconductors are materials that have some properties of both conductors and insulators. Germanium and Silicon are well known semiconductors. Superconductors are materials that pass electrical current with zero resistance. All known superconductors perform this function only at very low temperatures, far below those encountered in Earth environments (i.e. from around 77 degrees above absolute zero down, or, in other words, below about -320 degrees F).

NO. In a semiconductor the resistance decreases with increase of temperature. It is their natural behavior unlike conductors and insulators. If we decrease the temperature their resistance increases. At 0 degree kelvin all semiconductors will act like perfect insulators.
Insulators are hindered by their inability to conduct electricity or heat efficiently due to their high resistance to the flow of electrons or thermal energy. Additionally, insulators may be hindered by their bulkiness and weight compared to conductors or semiconductors.
In superconductors, no electricity is wasted because there is no resistance to the flow of electrons. In conductors any electricity not used, is wasted.
No, the resistance of an insulator is very high.
On the contrary, insulators have higher resistance than conductors. Resistance refers to resisting a flow of electricity, making it more difficult for electricity to flow. Conductors conduct electricity, they make it easy for electricity to flow. Insulators prevent the flow of electricity.
Electrical materials can be classified into conductors, insulators, and semiconductors based on their ability to conduct electricity. Conductors, like copper and aluminum, allow electricity to flow freely due to their low resistance. Insulators, such as rubber and glass, prevent electrical flow and are used to protect against electrical shocks. Semiconductors, like silicon, have properties between conductors and insulators, allowing them to conduct electricity under certain conditions, making them essential for modern electronics.
