I don't want to spin this out, but a couple of comments are in order.
On Acts 17:34: "which easily can be understood as "But some men (ANDRES)...believed, among who also [was] Dionysius the Areopagite; also [i.e. in addition, as a *separate* category] a woman named Damaris" etc." This seems to me to neglect the last part of the verse. If there are a group of MEN, who believed (including Dionysius), and, a separate category, a WOMAN named Damaris, to what category do the "and others with them" belong? "With them" links these others in a single group: those who believed.
That's certainly the most straightforward understanding of the KJV translation here: "Howbeit certain men clave unto him, and believed: among the which was Dionysius the Areopagite, and a woman named Damaris, and others with them". The "which" in "Among the which" is the "men" who clave to Paul and believed. In other words, the KJV is using "men" here in its generic sense, which potentially includes women.
On apposition, I think you have misunderstood my point. The second term more narrowly defines the first and so becomes unnecessary (and incorrect English style) to translate when the second term contains that information. So an isha almanah is not "a woman, a widow" but (in contemporary English) simply a widow. So even on your view, the proper translation of andres adelphoi is not "Men, brothers" (and still less the KJV's "Men and brothers", which erroneously suggests that two distinct groups are in view) but simply "Brothers", since brothers are by definition men. If however as I have sought to demonstrate above, andres can refer inclusively to both genders and (as all the reference grammars agree) adelphoi can (in some cases) be used inclusively of men and women, then the translator needs to seek to determine whether in this case the terms are being used inclusively in context. If not, he should translate "Brothers." If so, "Brothers and sisters" is probably better English style, since we do not use "Brothers" inclusively.
I am not saying that aner, andres and adelphoi are always inclusive. That would be ridiculous. However, in at least one other place aner is used by Paul inclusively: Romans 4:8, quoting Psalm 32:2 "How joyful is the person that the Lord does not charge with iniquity" (CSB). Clearly Paul here is not intending to say something about men in distinction from women. Indeed, the Hebrew has 'adam, not 'ish. But even 'ish can be used in a gender-inclusive way, as the KJV recognizes when it translates 'ish as "Whosoever" in (Lev. 22:21, among other places).
Gender language is tricky to translate. This is not an easy topic where there is an obvious "right" answer. Some will prefer to retain the traditional language and explain, where appropriate, that "brothers" actually means "brothers and sisters" here. That is a defensible position, but it isn't the only responsible position that people who are wholeheartedly committed to complementarianism can take.
