Styrofoam is a poor conductor of heat, which helps to retain the heat of the drink inside the cup for longer periods of time. Additionally, the insulating air pockets within the structure of the Styrofoam cup create a barrier that slows down heat transfer. This combination of factors results in the drink staying hot for a longer duration compared to other types of cups.
A Styrofoam cup will do both. The Styrofoam is an insulator, and, as such, it slows the transfer of heat between the system (the drink) and the surroundings (everything outside the cup) If it is a cold drink, heat moves very slowly through the cup toward the drink. If it is a hot drink, heat moves very slowly through the cup toward the surrounding air.
A metal cup would likely keep the hot water warmer for a longer period than a styrofoam cup due to its superior insulating properties. Metal is generally a better conductor of heat, so it is able to retain heat better than styrofoam, which is a poor insulator.
Putting the cup in the freezer keeps ice from melting. Those cups will slow down the melting rate, but if you've got ice at room temperature it's gonna melt eventually. Having said that, ice will melt slowest in a styrofoam cup.
A styrofoam cup can help to retain heat, but it is not as effective as materials like ceramic or insulated metal. Hot water in a styrofoam cup will cool down faster compared to using a better insulated material.
Hot cocoa will stay hotter for longer in a glass compared to a styrofoam cup because glass has better insulating properties than styrofoam. Styrofoam is a poor insulator, allowing heat to escape more quickly.

Styrofoam cups will keep a hot drink warmer for a long time. Insulated cups will also keep your drink warmer longer.
Styrofoam cups and caps. It keeps the heat in.

If the Stainless Steel cup has no insulation the Styrofoam cup will keep it warm longer.
Styrofoam cups are generally the best at keeping hot drinks warm for a longer period of time. This is because Styrofoam is an excellent insulator, meaning it does not conduct heat well and therefore helps to keep the temperature of the drink constant. Paper cups and plastic cups are also decent insulators, but they are not as effective as Styrofoam. Glass cups are poor insulators and are not recommended for keeping hot drinks warm.
A metal cup would likely keep the hot water warmer for a longer period than a styrofoam cup due to its superior insulating properties. Metal is generally a better conductor of heat, so it is able to retain heat better than styrofoam, which is a poor insulator.
