Sometimes. Many volcanoes form islands, but not all do.
Yes, changes in water color around a volcano can be a sign of volcanic activity. Volcanic gases and minerals can alter the chemistry of the water, leading to discoloration. This change in water color can indicate increased activity and potential hazards associated with the volcano.
No, geysers eject hot water and steam. Volcanoes eject lava. If enough water gets into a volcano, the water turns to steam and the volcano becomes an exploding volcano, not a geyser.
Water will be brought down with the subducting slab and it will lower the melting temperature of the rock, therefore making it easier to make a volcano. Again, that's very simplified, but its effectively that.
The bowl-shaped area around a volcano's central vent is called a crater. Craters are formed by explosive volcanic activity that creates a depression at the summit of the volcano. They can vary in size and shape depending on the eruption and the type of volcano. Some craters may also fill with water, forming a crater lake.
Before a volcano erupts, there may be high frequency and low frequency earthquakes, changes in shape or size of the volcano, and tremors.
a volcano that starts and erupts under water
yes, Hawaii was formed from a volcano
krakatoa volcano in indonesean archipelage

Clay or play doh, water bottle and form the clay around the water bottle in to a triangle
You know it's about to erupt when, sulphur dioxide seeps out of the volcano (It can contaminate the water). Trees and animals growing around it will die. Earthquakes (even tiny ones) will occur. Great fumes of ash and smoke will steam out of a volcano.
the volcano comes to your house and yells at you!

probably not the VOLCANO but maybe lava erupting from the volcano, but only around the volcano, within a few meters.
It is unclear what it means to "help" a volcano, but water does tend to make eruptions more explosive.
Olympus mons- on the moon- lacks water which makes it a better shield volcano. so these lack water.
The steep walled depression surrounding a volcano vent is called the crater. In dormant volcanos, these may fill with water and become crater lakes.
