I am still somewhat uncertain of the answer. Do these countries possess geysers because they are a part of the Ring of Fire? Or perhaps due to the fact that many magma chambers are located there?
Many of the geysers are not near the ring of fire.

This is from the first paragraph of the Wikipedia article.

"Generally all geyser field sites are located near active volcanic areas, and the geyser effect is due to the proximity of magma. Generally, surface water works its way down to an average depth of around 2,000 metres (6,600 ft) where it contacts hot rocks. The resultant boiling of the pressurized water results in the geyser effect of hot water and steam spraying out of the geyser's surface vent (a hydrothermal explosion)."

Yes. But note that most of the U.S. geysers are in Yellowstone National Park.
