Production Line Calculation

Is there a way to calculate 1 day as 8 hours of working period for the "Worker 1 time" X "Quantity of Product" = Answer
Therefore it needs to calculate as if there is a 1 hour job it calculates that there is still 7 hours that is able to work another job while there can be multiple small jobs for 1 day.

And for the "Delivery Date" i want to Deliver at Least 5 Jobs a Day Maximum is it possible to do so?

Im going to attach a sample document.
