PLEASE HELP ME... =(
I REALLY NEED TO DO THIS ONE :~
THANK YOU!

Please use code tags when posting code.

Your second code uses some of the same pins (for different purposes) as your first code does.
Before you even start to combine the two, you'll need to move the conflicting pins. You haven't stated which Arduino you're using, but I'll assume it's a Uno. The analogue pins (A0 -A5) can be used as digital pins (14 -19).

Easy part:
Combine the stuff that happens before void setup,
combine the stuff in void setup,
combine the stuff in void loop.
Anything outside of that should be standalone functions.

Tricky part - getting rid of duplications as Henry_Best said, and then making sure it does what you want:
I'll get you started on the easy part:

By combining two sketches, you are asking Arduino to not focus on one task at hand, but do two tasks together. Conflicting pins, variable and function names will need fixing. Delay() will need to be replaced with other code. But most importantly, what does sketch one do? Same to sketch two. There is no way to combine two sketches when we don't know what they do. I am not nice enough to read and decipher the code to answer this question myself. You posted the code so you should point out what each sketch does.
