Once food is cooked,you have in the range of three days to use,if stored properly in the fridge. Last night's cooked chicken is therefore fine until Thursday night.
I'd cook the fish tonight,as it is the most fragile when it comes to keeping for any length of time-eat tonight and tomorrow.
The pork and diced chicken can be cooked tomorrow-to be used by Saturday.
So-eat the fish tonight and tomorrow,the cooked chicken by Thursday,and the pork and diced chicken on Friday and Saturday.
