Don't waste your time on AWSurveys. They are a well known scam. As for the other two, I believe that they are legitimate - I cannot find anything about them that says that they don't pay. MyLot, of course, is 100% reliable but won't make you rich. Be sure to read the Guidelines carefully and to follow them. What you can earn is very much up to you. If you are active every day and make good quality contributions to discussions, it is possible to earn the minimum of $10 every month - several people do - but it is not easy at first. You would do well to read through the FAQs, especially the section on earnings, so that you understand how it works.
