Rule Set processing order

If there are multiple rules in a rule set, how are the rules processed?

If all the rules applied to a case, is only the last rule logic applied?

Example:

Rule Set: RuleSet1

Rules:

Lunch Hours Rule -> (if a person works over 5 hours, then one hours is subtracted)

Night Shift Rule -> (if a person works from 9 PM to 6AM get Night Premium pay)

Holiday Rule -> (if a person works on Holiday get a Holiday Pay)

If someone works 6 hours at night in a holiday. Will the Holiday Rule apply because is the last in the list? Even though the Lunch and the Night Shift Rule also applied to the specific case.
