Is she interested in me?

I'll try to keep it short.

Today during my practical in comp lab(that particular lab is very big so two different classes were sitting together) a girl from a different division than mine randomly called me and asked me if I was from Punjab (as I wear a turban)and whether I could speak in Punjabi or not, so I said I can speak Punjabi then she says its good to see Punjabi people in our college, later I asked her whether she is Punjabi, she said she is from Kashmir but in her family everyone speaks Punjabi and she came here for college. Then I got back to my work and remembered I forgot to ask her name, so I asked her name; as soon as she told me her name, our teacher came and told us to focus on our work. So when I was leaving the lab after my class ended, she called me, gave me her phone, and asked me to give her my Instagram ID. Her friends in the back started teasing her ki, "Abhi to milli hai aur insta id bhi mang liya.". Now I am wondering why she asked me for my Instagram ID. Is she interested in me? And if u guys think she is interested in me then pls give me some advice on what I should do next, cause I have 0 rizz, and next to none female interaction so I don't know what to do.
