No. Deimos is too small to have any sort of geologic activity.
No. Deimos is not a planet; it is a small moon. It does not have any volcanoes or geysers.
No, geysers send up fountain like jets of water and steam. Volcanoes erupt lava.
What I have learned in Earth Science I would say that there is many volcanoes and/or ice geysers.

Deimos, one of Mars' two moons, is a small and heavily cratered body with a surface dominated by impact craters. There is currently no direct evidence to suggest the presence of volcanic activity on Deimos. Volcanoes are typically formed by the eruption of molten rock, or magma, from beneath a planetary surface, and the lack of volcanic features on Deimos indicates that it may not have experienced such volcanic activity in its history.
