running 5 python programs together via shell scripting

Question

I have 5 python programs and i want to run them all simultaneously./concurrently

lets say i have these programs

python1.py
python2.py
python3.py
python4.py
python5.py

How can a shell script run them all together? if i just put 5 commands like this

all.sh
 python python1.py
 python python2.py
 python python3.py
 python python4.py
 python python5.py

will they work all together?

Is there any better alternative?

great. what does the & symbol do?

Starts a job in the background.

just to make sure: all of them will run in a parallel way?
