Helium is less dense than air, which is why the helium-filled balloon floats when you let it go.
volume decreases considering the pressure is constant
A balloon can be blown up until the pressure of the contained air becomes too great, and the rubber breaks. I can imagine that the volume of air a balloon can hold depends on the size of the balloon before it is inflated, the thickness of the rubber, and the quality of the rubber.Various types of balloons will therefore have different capacities. I would think that an average party balloon could probably hold 3 or 4 litres of air. If you wanted, you could find the radius of the balloon, then calculate the volume (presuming that the balloon is a sphere). You could also fill a balloon with water then weigh it.
Because the gas inside expands with the heat
the volume of air inside the balloon increases while the pressure of balloon decreases thus balloon inflates
The kinetic energy of the particles inside the balloon increase. This then expands the volume of the balloon.

I interpret this question to be asking how one might measure the volume of a water balloon without breaking the balloon or emptying it of the water in order to measure its volume. One method is to fill a container with water that will be large enough to contain the water balloon, and then submerging the water balloon in the container. The volume of the balloon will be the apparent volume change of the water in the container. Any measurement will introduce some error. Since water compresses hardly at all, one would expect that submerging the balloon would not significantly change the volume of the balloon. There could be some error if one had to push down on the balloon to make it fully submerge. There will also be some measurement error in determining the volume change.

The volume become 197 mL. (Avogadro law)
the volume of air inside the balloon increases while the pressure of balloon decreases thus balloon inflates
For a balloon that is sealed and not full the volume of air inside the balloon will increase as it is heated. This is not however how hot air balloons work. A hot air balloon is essentially a fixed volume when it is inflated. If the air inside the balloon is heated the air inside becomes less dense so some of the air exits the balloon via the mouth of the balloon. As the air inside the balloon cools it becomes more dense so some air is ingested via the mouth of the balloon to keep it full. With each heating and cooling cycle, the pressure inside the balloon remains constant, the volume of the balloon remains constant but there is this movement of air out of and back into the balloon.

If a balloon is squeezed, then that means the volume is decreasing. Volume and pressure vary indirectly, which means that when one goes up, the other goes down. So when you are decreasing the volume of the balloon, the pressure inside is going up (assuming constant mass and temperature).
