Hi,

You can use following code in your apex controller to get error message to respective field.

ObjectInstance.FieldName.AddError('Your Error message')

for example if you have contact object and you want to display error message in lastName field then you can do like following

Contact con = new contact();

con.LastName.addError('Please fill contact Name');
