I assume that each of the jobs in the application have something similar to "RUN DAILY" or "RUN TODAY" etc so that they are selected whenever the event is triggered
For the two jobs you want to further restrict, I would use something along the lines of the following for the run-frequency
IF DAYS_TO('4TH WORKDAY OF MONTH STARTING 1ST DAY OF MONTH') >= 0 -
OR %ESPSHH < 13 THEN RUN TODAY
The DAYS_TO part limits the job to the 1st 4 working days of the month and the %ESPSHH part limits the job to being selected only between midnight and midday
Obviously this does not exactly suit your needs, but it illustrates the principle of building complex scheduling criteria using functions such as DAYS_FROM, DAYS_TO, DAYS_BETWEEN etc and the ESP built-in scheduling variables along with the standard mathematical and logical operators.
