finding lost friends

I was in Anna adharsh school(chennai)till 5th standard. Then I left from there. I still have great memories from the school. ofcourse I dont have any contact details of my friends. its been 9 years since I shifted. IDK if they’ll remember me. but I’d like to give it a try on finding them. i dont have anything else than their name and a normal school group photo. so tell me ways in which I could find them please!!! If any one of you is from Anna adharsh school, Arumbakkam during the same timeline kindly DM. Thanks in advance.
