That's a cabling certification report. The failing cables do not meet the tolerances for certification. The practical impact is that the cables may not reliably work when connected to computers and switches. You may see errors, slow speed, unreliable connections, etc, when using these failing cables.
Since you don't have familiarity with cabling standards your best bet is probably to have a cabling contractor come in and re-terminate the failing drops or, if necessary, re-run the wires. An experienced contractor (properly trained and industry certified) can look at that certification report and decide what the best course of action is.
