For the first error,
In Employee List, there is 'dot' at the end of the name ( Platero, Jose Cruz Jr. ). But in the import file there is no dot.
So please either remove dot from employee list or add dot in the import file to load the file successfully to required module.
For second error, there might be two rows of data in import file for a given employee. When multiple data exists in import file for given employee, this type of error will get occurred.
Just adding to this, it is always recommended to use a code rather than a name, especially with employees as their names can change, but their ID rarely does
Always use CODE for Insert / Update the data in the List. CODE will not change compared to Name / Duplicate names.
