A water spray may be used to help slow the speed of a lava flow as it will cause cooling of the lava front increasing it's viscosity and so reducing it's flow rate. However a LOT of water would be required.
The way water assists in forming a volcano is very simple. Water lowers the melting temperature of rocks. It is typically brought down the sub-ducting slab in it's formation mission.
It cools the lava, forming rock, which the volcano is built upon.
Water that comes in contact with magma or very hot rock can flash boil, causing an explosion of steam.
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.
Volcanos CAN form under water. that is how land is formed.
No There are many volcano's under the ocean
Sometimes. Many volcanoes form islands, but not all do.

It is unclear what it means to "help" a volcano, but water does tend to make eruptions more explosive.

No There are many volcano's under the ocean
No, because when a volcano reaches the surface of the water it forms a volcnic island not a mountain
Sometimes. Many volcanoes form islands, but not all do.
How did the volcano kohala form
No. It is called a volcanic island.
WHat is a volcano
It is unkown how they formed, although it is believed that they formed from an underwater volcano eruption.
Mountains form when the volcano reaches the surface
