Please does anyone know how to lead a team of beginner joggers?

I like to jog to keep my weight down and my heart healthy
Jogging alone got boring and unsafe so I sent out an email to my neighbours asking for people who were interested in jogging.
To my surprise I have 5 interested candidates already out of 15. I wasn't expecting more than 2.

Problem now is, I'm no fitness instructor. I don't even have a loud voice and I don't think I know how to motivate people.
They might expect me to lead them and I am honestly clueless
Should we stretch first before/after we jog?
I just want to make happier people with healthier bodies.
