Is it allowed to read namaz with a non mehram?

Assalam alaikum. I'm a 17_ year old girl from India . I go to tuitions in the evening here timings is from 5-8. And hence I had to read the Magrib Namaz(prayer) from the tuitions. And along with me there is one more guy who reads his namaz. We pray in the same hall but at the different corners. My question is that is it allowed to read namaz along with a non mehram? And is there anything that me or him are going against Islam which we are not aware of? Please do reply. Allah hafiz
