I'm familiar with most Orthodox jurisdictions of any size here in the US, and I have trouble thinking of 3 jurisdictions that don't recognize the others as being Orthodox. Well over 90% of American Orthodox are in one of four jurisdictions (Greek, Serb, OCA, Antiochian), all of which fully recognize each other -- and there are multiple other smaller jurisdictions that also are mutually recognized as Orthodox.
You apparently live in a very odd place, if you have three local Orthodox parishes, none of which recognize the other as being Orthodox. I'm surprised that your Orthodox bishop and priest buddies haven't been able to clarify the situation for you.
There are TWO Ukrainian Orthodox Churches. I know the problem with one (from my bishop-friend who is no longer in New England and has not been for a long time; he was moved to Chicago and is not part of any of the three at all, he's OCA) has to do with a "self-ordination" at the hand of a dead bishop. A parishioner from the other one said their priest was pushing the idea of affiliation with the Autocephalous Orthodox Church of Ukraine (independent of Moscow).
And one that is affiliated with a very strict monastery in Boston (where they've always had the picture of the Czar inside the front door with an oil lamp in front of it).
None of them are OCA or Greek Archdiocese.
