Your solutions are correct to the point that they are working. The following is just a bit of additional information you might find useful. I noticed, that you have no solution for question 2.7, probably an oversight?
RudiC is correct: "kill -9" means the OS actively terminates the process. "kill -15" on the other hand tells the process to shut down immediately. In your case this will not make that much difference, but if a process has open temporary files or logs to be written, or any other allocated resources, "kill -15" will allow it to neatly close all these before exiting while "kill -9" will leave all these open and hanging in limbo.
I don't know which shell you use, but most probably it is either bash or ksh. In both cases you can make use of the job control of this shell: issue "jobs" to see a list of jobs in the background and use "kill %<number>" instead of "kill <PID>" to address the process.
The "kill" command can take a list of PIDs to process. Instead of

kill
KILL(2) System Calls Manual KILL(2)NAME
kill - send signal to a process
SYNOPSIS
kill(pid, sig);
DESCRIPTION
Kill sends the signal sig to the process specified by the process number in r0. See signal(2) for a list of signals.
The sending and receiving processes must have the same effective user ID, otherwise this call is restricted to the super-user.
If the process number is 0, the signal is sent to all other processes in the sender's process group; see tty(4).
If the process number is -1, and the user is the super-user, the signal is broadcast universally except to processes 0 and 1, the scheduler
and initialization processes, see init(8).
Processes may send signals to themselves.
SEE ALSO signal(2), kill(1)DIAGNOSTICS
Zero is returned if the process is killed; -1 is returned if the process does not have the same effective user ID and the user is not
super-user, or if the process does not exist.
