Appointments+ settings questions

I'm trying to finish setting up Appointments+ for my clients new website. I have 3 questions:

(1) In confirmation emails can we add shortcodes to note details like remaining payment, bookers name etc? If so, where can I find the shortcodes? Can I also format the text in the emails, e.g bold etc?

(2) Can we show all services on one calendar? My client has 1 studio, but has 4 booking rates for days of the week (so I have set this up as 4 services).

(3) Can we change the specific start times of bookings? The calendar starts at 8am for some reason, but my client wants it to start at 9am
