Answer 1

one active control file is enough for database to run, you can do copy/paste on line, but make sure that what you do. make sure that all the control files are in same in size.
i suggest you make a copy of existing control file and then perform copy.
For example the control files details:
SQL> show parameter control_files;
NAME                                 TYPE        VALUE
control_files                        string      /oracle/PRD/sapdata1/cntrl/cntrlPRD.dbf,
                                                       /oracle/PRD/sapdata2/cntrl/cntrlPRD.dbf,
                                                       /oracle/PRD/saparch/cntrl/cntrlPRD.dbf
