How do I change core field labels?

For example, the user sees "Individual Price" and I would like to change it to "Cost". Or should I just create a custom field? I like to use text for fields like "Time" because there's a description ("Doors open at 6pm, concert begins at 7"). (I have a custom Time field.)

Similarly I'd like to change the title "Event Properties" to "Details" or nothing at all.

Thanks.

Hello

For all of these text, you can just go to Events Booking -> Translation, find the text and change it to meet your need
