Yes, up to four, with a firm condition of justice among them. The Quran says that whoever fears he will not be just should marry one (4:3), and notes that perfect fairness in feeling is not possible (4:129), so the duty is justice in spending, time and treatment. Local law and agreements may add conditions.
