How to set sequence of interrupt for PIC

I did study about pic basic code but confuse about sequence of interrupt. for now i did make project with 5 sw buttom, IR for control o/p , time ds1307,Temp DS18s20 and 7seg (muliple scan dis)for display time and temp.
Now,our code work with for all but run with individual code.
I have try to combine all code together found problem with flashing on 7 seg or slow reapond of o/p and hang .

I think fail of interrupt management How can advise me about interrupt flow for me

I used pic16F877A / 4 Mhz used bootloader of microcode for try

And the code is a state secret?

Here is my code , Time/temp display and IR decode

Pls advise ...
