Welcome to Apple Support Communities.
I did some research. I apologize for the link issue. There is a Safari 6.0.1 for Lion. It could be installed with 10.7.5, but if you don't have it then try using Software Update. If it isn't available that way, then it was an experimental version. In other words there is no 6.0.x public release for Lion; only for Mountain Lion. For example you can click on 10.7 under the Mac OS X heading and then choose Safari in the browsers section and see that Safari 6 is the only version supported. However, if you select just 10.7 you can see that there is a lot more versions available for Google Chrome, Firefox and Opera.
If I'm understanding correctly, several apps are not working because you need to update your macOS. I will be happy to help you with this. Your current version of macOS can be updated to macOS Sierra.
Take a look at the information below to ensure that you meet all of the other necessary system requirements to upgrade to macOS Sierra, from our article: How to get macOS Sierra

Get Sierra from the App Store
Before upgrading, it's a good idea to back up your Mac. Then follow these steps:
- Open the App Store app on your Mac.
- Search the App Store for macOS Sierra, or go directly to the macOS Sierra page.
- Click the Download button on the macOS Sierra page. A file named Install macOS Sierra downloads to your Applications folder.
- After download is complete, Install macOS Sierra opens automatically. (You can also open it from the Applications folder, Launchpad, or Spotlight.) Click Continue and follow the onscreen instructions.
