Please check the spelling in your repository URLs. According to the error messages you posted, several of your repo URLs seem to start with htp://. It needs to be at least http://. Once you corrected this, you may need to look into encrypted connections (for those, you'll need https:// as the protocol prefix), signed repositories and key management and so forth. But those will probably be topics of their own.

You'll find the definitions of the repositories your system "knows about" in /etc/apt/sources.list and/or in individual files in /etc/apt/sources.list.d.
