Hi Iliop,
Welcome to the board. 
This should take care of the hours part of the table. In B1 enter this formula and fill across / copy across to Y1Apply formatting as h:mm AM/PM.
I cannot follow requirements for the rest of the table, and I have not come up with anything that duplicates posted results, and I am at a loss to know what questions to ask. Can you elaborate? Any formula I come up with recognizes the shift code names. So every cell gets filled with something which is not what you want. Do you have another table that lists each shift code name with their valid work(?) hours?
Edit I modified the formula to wrap around midnight. Before it incremented to the next day at midnight.
