Are those functions used in arduino code and processing ide connecting and the music files are in same folder....
I think its cost effective and it should work....
You can use analog pins also which are remaining but if you need to connect more I suggest arduino MEGA which has more pins...
Yes it's possible to play it directly through arduino if you use mp3 shield like this one https://www.adafruit.com/product/1788
I am little bit busy to make a different tutorial on it.....If you have any doubt in specific line in code let me know here....

Connect as per the fitzing diagram each module has common vcc and ground connection is connected to arduino then each modules trigger and echo pin connection is connected to different pins of arduino....
delay will be due to the delay required to run the music file and processing application eats up ram even i got some delay initially(Point to remembered barriers should not be far and should not be removed or else there will be huge lag or error full measurements)Hope this solved your problem.

Awesome suggestions and I suggest these for anyone who's building this....Again Thanks for suggestions for quick prototype I had only uno lying around ....nextime I will definetly do some homework...
Glad you liked it please vote if you think its worth....Thanks a lot

Pir sensors works as trans receivers so.. I will tell you what I have understood from your query... Staircase lighting circuit is required which automatically turns off while person reaches top of the stair but your question is what if person from top of the stair walks down at the same time.....Solution: Install another pir between the staircase (halfway) and control all the pirs relays using one arduino program it by checking && logic and || logic with pir installed in halfway....with top pir or down pir....sequential if loop....If you have any doubts you can ask again....All the best...
