How is it compile? Can some one can do that make the hex file?

You are in a hard place.
No. The code I posted is not just for reference, it does function and you can use it as the basis for a source file you can build with your MPLAB tools. But I did make this more difficult for you by posting the list file output from the assembly rather than the source file.

; If the switch is Press and hold (My timer output is enable for 1 Minute minimum) either Press, all LED will be ON.
; After 1 Second, LED 1 Turn Off,
; After 2 Second, LED 2 Turn Off
; After 4 Second, LED 3 Turn Off
; After 6 Second, LED 4 Turn Off
; After 8 Second, LED 5 Turn Off.
