Some of these errors cannot be solved Rick
It appears (from my short research) that for some reason the server collation used in your current instance is incompatible with 2014 so you can’t do an inplace upgrade

“The SQL Server Database Engine server collation property cannot be changed. You will not be able to complete an upgrade of Reporting Services. You will need to migrate your Reporting Services installation to a new server which is using a compatible server collation.”
Frankly in place upgrades of DB Engines always give me jitters. Recommend you setup a new server install 2014 then move the DB over.
(If you don’t have additional hardware then you could uninstall/ re-install… I suppose)
