Google Ten States Standards. It should have the information you need.
There are also US government Unified Facilities Criteria (UFC), some of which are old technical manuals.
These will have the procedures you can follow if there are no local standards.

From your list, this is what I would expect:

Ave. Consumption 600 L/d per person * Total Population (persons) 538.0 * Min. Rate 0.4 /86400 = Min. Daily Demand (L/sec)

Ave. Consumption 600 L/d per person * Total Population (persons) 538.0 * Max. Day 2.75 /86400 = Max. Daily Demand (L/sec)

(Ave. Consumption 600 L/d per person * Total Population (persons) 538.0 * Max. Day 2.75 /86400) + (Fire Flow 75.8 L/s Max. Daily Demand (L/sec)) = Max. Day Demand + Fire Flow (L/sec)

Ave. Consumption 600 L/d per person * Total Population (persons) 538.0 *Peak Rate 4.13 /86400 = Max. Hourly Demand (L/sec)
