These are warning messages, not errors. Which version of VirtueMart are you using?
The three shipping plugins installed on your site are causing these warnings. Two of them are third-party extensions. If you've installed the latest version of VirtueMart, the last warning should disappear. For the other two, you will need to contact the respective developers for assistance.
