Foam will insulate better than plastic.
The weight of a plastic cup can vary based on the size and thickness of the cup. On average, a small disposable plastic cup weighs approximately 5-10 grams, while a larger plastic cup can weigh around 15-30 grams.
The weight of a plastic cup can vary depending on size and thickness, but typically ranges from 5 to 20 grams.
A glass cup will conduct heat away quickly - a plastic cup would hold heat the best.

Styrofoam insulates better than a single layer of plastic. If, however, you have one of those plastic cups that have an outer and an inner "wall" with a sealed air space in between, that should work better than the Styrofoam.
Heat will travel faster through a glass cup than a plastic cup because glass is a better conductor of heat than plastic. This means that heat will transfer more quickly through the glass, making it heat up or cool down faster compared to the plastic 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.
You're talking about holding the temperature of the water, right? As far as containing the liquid, they're about equal...but a styrofoam or double-wall plastic cup would hold temp better than a glass cup which would work better than a single-wall plastic cup.
metal cup because it has insulation
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 plastic cup holds more heat because plastic can't take out heat. Glass conducts heat away.
