Answer 1

You cannot have PLSQL create new sessions. You have to explicitly create new sessions -- running SQLPLUS from the OS.
As for the procedure, you'd either
a. Have the procedure read a parameter that is passed to it and use that parameter to identify which line from the table it should run (the parameter has to be passed in from another procedure or from the command line).
OR
b. Have 5 different procedures, each procedure hard-coded for 1 line from the table
OR
c. Have each procedure put a "I am running this line, do not run it" message (e.g. in an additional column) for each line to prevent another session running the same line -- the first procedure has to commit that flag and also has to delete it after running the line.
