These confusing words all have completely different meanings.
In brief, a boar is an adult male pig—of any pig species.
A boor is a rude and annoying person.
And bore has two meanings, each with both a noun and a verb:
Bore-1 (verb): to be uninteresting; or to make a person feel uninterested
Bore-1 (noun): an uninteresting person or thing
Bore-2 (verb): to make a hole in something
Bore-2 (noun): a specific kind of tool used to drill (bore) holes
Bore also has a slightly less common meaning, related to meaning 2 above; that bore is the inner surface of a hollow cylinder or tube, such as in the barrel of a gun or cannon, or in the kind of large drills used to bore deep holes in the ground.
Finally, bore has yet another minor meaning, referring to a special kind of water-wave that happens at the mouths of some rivers when the tide comes in and becomes compressed (squeezed together), pushing an unusually high and forceful wave of water up the river (or small bay); this is called a tidal bore, probably because it bores up-river, like a drill boring a hole, metaphorically.
Finally, as a side note, boor is also the name for a kind of pheasant (a kind of bird); however, it is unlikely you will need to know this meaning, as few people do!
