I was changing the water pump and I think I messed up on putting the timing belt back on because now the car won't start, it just makes a noise. Which is in the video attached.

After putting timing belt back together it started shaking engine badly and smoking under hood and popping noise from exhaust.

It sounds like the belt is not installed correctly. On these engines there is a procedure, I don't think you can just put the marks on and put it together. If you are confident the timing belt is on correctly let's pull the spark plugs and do a compression test. Here is a guide that can help:

Please go over these guides and get back to us.

What if the timing belt looks kind of torn on one of the teeth can that cause it? It just a little tear in the end.

Yep, any tears or signs of wear are bad on a timing belt. I would replace it.
