I mean sit next to them to eat with them (lunch in school)
You can sit with them to eat lunch. Islam doesn't forbid kindness towards others.
Inviting them to your house is a different issue. You have to think about the whole non-mahram in the house and privacy for the women of the house.
when you're in your own house, you are among those considered mahram.

I believe he meant your friend being the non-mahram among your women if you invite him to your house.
Hmmm...interesting question, but I'm afraid people have not given you a more nuanced answer.
In Islam, there are rules about purification and there is a concept about contamination through contact with that which is impure. As you know, the Holy Qur'an states that the Mushrikeen are impure, hence why they are forbidden from even approaching near to the sacred Mosque.
Our beloved Prophet صلى الله عليه وآله وسلم instructed us to avoid the utensils that have been used by Jews, Christians and Magians. If we have no choice, then they have to be properly washed.
Now of course these days washing dishes that someone else has used is customary, and people usually eat from separate dishes.
However, sometimes people eat together from the same dish so you have to be careful.
Ah I see. Understood.
Well, if she turns up with a mahram, then it's all good I guess. A woman turning up to a ghair mahrams house on her own, is kinda questionable.

She who?
The OP is a male and mostly would have a male friend he wants to invite over. And since we are talking about non-mahrams, it stands to reason that invited friend would be a male.
