If you like to get only numbers, you chould check the values of the object with Array#some and typeof operator.

const
    names = [{ name: 'Anna' }, { num: 27 }, { name: 'Valeria', age: 20 }, { secondname: 'Wilson' }, { age: 12, name: 'Max' }, { weight: '50kg', height: '172cm', name: 'Nick' }],
    result = names.filter(o => Object
        .values(o)
        .some(v => typeof v === 'number' && v > 15)
    );

console.log(result);

.as-console-wrapper { max-height: 100% !important; top: 0; }
