It really depends on what your objectives are. Do you want to build muscle? Lose fat? Or both?
If you just want to eat healthy stuff then sure, you can have 2-3 shakes a day or even more, just don't add sugar and/or alcohol.
Also, don't take more protein than the amount your body needs, it would be a waste of money (good supplements are not cheap) and useless calories. As a rule of thumb, don't go over 0.8g of protein per Kg of body weight in a day if you're working out, less than that if you're not.
Don't forget your healthy fats and whole grain carbs. Your body needs those as well.
