Not for long.
Paper cups are biodegradable, convenient, and can help maintain the temperature of cold drinks better than some other containers.
The duration for which a paper cup can keep ice cold depends on various factors such as the thickness of the paper, the ambient temperature, and the insulation properties of the cup. In general, a paper cup may keep ice cold for about 1-2 hours before the ice starts to melt significantly. However, using additional insulation like a sleeve or double-cupping can help extend the duration for which the ice stays cold.

The thermal conductivity decreases when a paper cup (or another paper cup) is added. Intuitively, the heat has to pass through more layers. This is Fourier's Law of Heat Conduction - lower thermal conductivity means less heat loss.

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.
Plastic is a poor conductor of heat, so a plastic cup can be considered a good insulator. It will help to keep hot drinks hot and cold drinks cold for longer periods of time compared to a material that is a good conductor like metal.
You can keep a cup cold by using a double-walled insulated cup, adding ice cubes, or placing the cup in the refrigerator or a cooler. Additionally, using a coaster or a sleeve can help insulate the cup and keep it cold longer.
A double-walled insulated cup made of stainless steel or vacuum-sealed material will keep drinks cold the longest by preventing heat transfer. Look for a cup with a lid to further maintain the temperature.
A paper cup typically does not keep water hotter than a plastic cup. Paper is a poor insulator compared to plastic, so heat is more likely to escape from a paper cup, leading to faster cooling of the water inside.
An insulated cup helps maintain the temperature of a beverage by reducing heat transfer through its double-wall construction or vacuum insulation. This helps keep drinks hot or cold for longer periods of time compared to a regular cup.
Plastic is an insulator. but most of the paper is not insulated, because the paper in general contains water, although the content is very low, but enough to pass current, but there also is a special insulation paper, that is on the special purpose. so in dry conditions, and the cup has no water, a plastic cup is a better insulator than a paper cup.
