Reply to salam is compulsory (wajib) to everyone but if someone have paid salam in the group via message, is it compulsory (wajib) to reply?

Yes, if by not replying the group will think you are disrespecting the person who said Salam, then it’s haram to disrespect a fellow believer. Sayed Mohammad Baqer Qazwini Akhlaqenglish
