Sense: noun/1
All five words refer to an outer boundary of an object, but they highlight different aspects. 'Surface' is the broadest and most neutral term, covering the entire outer layer or top area of something, whether natural or man-made ('the surface of the lake', 'a smooth wooden surface'). 'Exterior' is more formal and emphasises the external covering that protects or encloses ('the exterior of the building'), often contrasting with the interior. 'Face' focuses on a specific side, especially the front or most visible side of an object ('the face of a clock', 'the north face of the mountain'). 'Side' is more general — any one of the flat boundaries of an object ('the side of a box'). 'Top' specifically refers to the highest horizontal surface of an object, not the sides ('the top of the table'). In everyday use, you can say 'the surface of the desk' or 'the top of the desk' interchangeably, but 'surface' is broader: the surface of a lake is its entire top area, while 'the top of the lake' would be unusual.
Common collocations
Etymology
The word 'surface' entered English from French 'surface', which was formed by combining 'sur-' (meaning 'above') with 'face' (meaning 'face or appearance'). The French word itself came from Latin 'superficies', a combination of 'super-' ('above, over') and 'facies' ('face, form, appearance'). The original Latin word already carried both the literal meaning (the outer face of an object) and the figurative meaning (outward appearance as opposed to reality), a double meaning that survives in English today.
