Working conditions are important, but money is also important because of what it enables us to do. For example, if you make more money, you can work less or work at a job you care more about in the future. More money is what you are certainly worth because of all the offers you are getting and can mean more leisure time for you in the future or the ability to have more freedom. Please consider discussing this with the people who have made these offers and try to consider what money will buy you in the future, other than just things that you don't need.
You should be very proud of yourself that you are so respected for being a good worker and a responsible person, and that is worth a lot to an employer!!
