The same as it does in atmosphere. Do you mean in zero-gravity perhaps?

That depends on the amount of water, the temperature, the shape of the container that holds the water.
In air, yes. In vacuum, no.
Both a gas (carbon dioxide) and a liquid (water) will take on the shape of the containers.
A liquid (water) takes on the temperature you give it. You need to boil the water if you want to brew a cup of tea. Having brewed your cup of tea, it will take on the shape of the cup you use. Therefore, gas and liquids take on the shape of the container.
As a liquid water has no defined shape. It will take on the shape of the container it is put in.

Water will try to take a shape that represents the lowest energy. If water were in a vacuum this shape would be sphere. As the air runs past the falling droplet this sphere sees atmospheric drag. This distorts the shape of the sphere. Furthermore, the droplet if possible, would "like" the air to flow past it in laminar, non turbulent stream. Since the drop is elastic to tends to form a shape not unlike the cross section of an airplane wing. This is a shape that tends to be in the lowest energy and to provide for smooth flow of air over the surface of the drop.
Yes, helium will take the shape of its container. It is a gas and therefore does not have a definite shape or volume. It will fill any space available to it within the container.

Water is a liquid, and its molecules move around freely, but still must respond to gravity. The molecules in liquid water do not have the ability to hold a shape by rigidly clinging to each other, so the liquid will take the shape of its container.
a vacuum former is a machine that is used to heat up plastic and mould it to the right shape.
The wind or air shapes the water
Vacuum molding is the process of using a vacuum to suck a pliable material into a specified shape. For example, the plastic hull in a boat is made when the warmed plastic is pliable (shape can be altered for useful purposes) and is sucked up against a form in the shape the designer wants the hull of the boat to be in. While the vacuum holds the reshaped plastic hull against the form, the plastic cools and holds the new shape.
