In the Archdiocese of Oklahoma City all of them do.
Roman Catholic AnswerTo the best of my knowledge, all of them. I have never heard of a Catholic school that does not have Mass at least once a week.Many Catholic parishes have Mass every day not just Sundays. That's because we should have the opportunity to worship God every day.
There are millions of Catholics in the UK and many of them want to be able to go to Catholic schools, so naturally there is a lot of Catholic schools in the UK.
I can not speak for all the different Catholic schools but many teachers in Catholic schools earn about half that of a teacher in public schools in the same area.

No, there are business schools, pottery schools, and many other types of schools in Ireland.
Thousands. Possibly Tens of Thousands. Maybe more. A lot. There are several in every major city. I live in Baltimore and can think of more than ten in the area without even stopping to think about it. They are everywhere.

Few, most would be Christian/Catholic schools.
Holy Mass is celebrated at Catholic churches, chapels, and oratories throughout the world every day of the year, with the exception of Good Friday. Mass is never celebrated on that day; many parishes have Good Friday services instead, which may include Stations of the Cross and may include the distribution of Holy Communion.
Many Catholic schools do participate in the NJHS, others do not. That is left to the discretion of each school or parish.
