Yes, it is ok. But to avoid possible questioning at the airports, apply for a British passport for her and, if you are Irish too, also get an Irish passport for yourself.When you go abroad, take both with you, but for departure from other countries, use the one passport you used to enter them.
Not if you are a citizen of an EU or Schengen Area country which issues national identity cards, then you can enter Switzerland using that identity card. Otherwise you need a passport. If you are entering Switzerland via the land borders there are not normally any passport / ID card checks, as Switzerland and all countries bordering it are members of the Schengen Area. But you still need to carry your passport or ID card as this is a legal requirement in Switzerland, and you might be unlucky and get asked to show it at the border.

No, an Irish passport holder does not need a visa to enter Switzerland for short stays of up to 90 days. Both Ireland and Switzerland are part of the Schengen Area, allowing for visa-free travel for tourist, business, or family visits. However, travelers should ensure their passport is valid for the duration of their stay.
Assuming by a "European passport" you mean a passport from a country which is a member of the EU; then the answer is none. Switzerland is a member of the Schengen agreement. All EU citizens (plus those of other Schengen member countries) are free to travel to Switzerland with a valid passport or national identity card without restriction.

Yes you do have to have a passport to go to Chile.
It depends on your nationality. Switzerland is part of the Schengen Area. If you have an EU or Schengen area passport, there is no minimum validity. You can even travel to Switzerland on your national identity card, if you are from a country that issues them. If you are from a non-Schengen/EU country you need a validity of at least 3 months on your passport, and if you need a visa then you also need 2 blank pages on your passport.
