Funny thing about "hey guys".
I joined a work meeting yesterday (dev team, we're all nerds) and someone said "hey guys", and one lgbt (male) person in the meeting made a comment that it should probably not be said anymore.
There was one woman, and she immediately said that it felt natural for her and she didn't care.
I'm technically lgbt too and I was facepalming the whole time lol.

I am pretty indifferent towards the phrase and I consider it more so to be environment than anything else. If I am in the a group people, I don't really care because the term has become pretty "gender neutral" when referring to a decent size group of people. When it's literally just my wife and I sitting together, I am a little less happy about it, but not really that phased to the point where I would say anything or let it ruin anything. It's pretty rare in my area because "y'all" is so commonly used and thus hearing "you guys" from anyone is kind of weird and different for this area.
I know some people use the word elle as a singular they pronoun in Spanish. Though I don't believe it's very commonly used, at least from what I've heard.

There are words that will be equivalent to "They" in the Latin languages (i.e. Portuguese, Spanish, French, Italian, etc...), but they will be gendered. In the end, they all mean the same, but it depends on whom the sentence is addressed to. If you have a group of people of both genders, you end up using the masculine form. Don't ask me why, I didn't create the languages or make any rules!
