Question about time expression in British English

How do British people express these?

9:10 ten past nine/nine ten

9:30 nine thirty/half past nine

9: 15 a quarter past nine

9: 45 three quarters past nine/a quarter to ten

Are there any other unique ways people in Britain use to express these clocks? I just learned today that people in Britain also use "half + number" for "half past + number" (9: 30 half nine, for example), is it real?

Answer

9:10 - ten past nine / nine ten

9:30 - half past nine / half nine / nine thirty

9:15 - quarter past nine / nine fifteen
 
9:45 - quarter to ten / nine forty-five (I have never heard three quarters past nine in my life.)

Half nine (e.g.) is real.
