Regarding the Greek, in all four verses that you cite, the same Greek word is used for "one" -- the Greek word "en".
Of itself that doesn't prove much. In Greek, as in English, you can use a word to have different shades of meaning in different contexts, and two words can be synonyms.
One of the verses that you cite, John 17:11, says, "that they may be one as We are", which would pretty clearly indicate that the oneness of the church is in some way the same as the oneness of the Father and Son. One could debate whether this means that the oneness of the church is exactly the same thing as the Trinity, that it is comparable as a analogy but not the same thing, or that here Jesus is talking about a unity between himself and the Father that is not the same as the unity of the Trinity.
To the best of my knowledge, Scripture does not give a definitive answer to this question. Happy to hear if somebody else can point to verses that could clarify.
