That is called an ocean.
island is the correct answer.
Lake, mere, tarn, are three possibilities.
That depends on whether the land is surrounded by water or something else. If it is surrounded by water, it is an island. If it is surrounded by water but is sufficiently large, it may be called an island continent (an example is Australia). If it is a land area completely surrounded by high mountains, rivers will flow to the land that is surrounded instead of to the ocean in that area. That would make the land an endorrheic basin.
No, the depth of a water table can vary significantly even over a large area of land. Factors such as topography, soil composition, climate, and proximity to bodies of water can influence water table depth. Additionally, human activities like irrigation and groundwater extraction can also cause variations in the water table level. Therefore, it is not consistent across large regions.
a tract of land has no specific size, it is just an extended area
