Upgrade from 1.9 to 2.0 got some error code from SQL Script

To upgrade from 1.9 to 2.0, after running the SQL Script, I got the following error codes by end. (Most of the scripts ran successfully). Are those errors critical? or they are normal, I can ignore and continue my upgrade to 2.2, 2.3?

Anyone can help me? Thanks!!!

The following is a copy and paste of the SQL script error codes.
