You can use the $in operator:

Usergroup.findOne({
            mobilenumber: 0509867865
        },
        function(err, usergroup) {
            if (err) {
                return handleError(res, err);
            }
            if (!usergroup) {
                return res.status(404).send('Not Found');
            }
            console.log(usergroup.groupname);
        //group north ,group south
            Group.find({
                    groupname: { $in: usergroup.groupname.split(",") } 
                },
                function(err, group) {
                    if (err) {
                        return handleError(res, err);
                    }

                    return res.json(group);
                });
        });
