I don't understand the question. Anyone can apply for a PR TD if their PR card is lost or expired.
Again the "forced by parents" excuse really only works when you're a minor. After you reach age of majority (so when you're 18-21 or so) you are able to make your own life decisions. Especially into your late 20s, it could be seen as your personal choice to keep following your father's wishes to stay outside Canada.

Yes. The appeal process can take several years. During this time you can be issued 1-year validity PR cards while waiting. And you will have the same rights as other PRs while waiting meaning you can go to school or work wherever you like.
Sometimes establishing yourself firmly in Canada helps with the appeal process, as by the time your appeal is heard they will see you're committed to permanently living here.
Of course this is not guaranteed so if the appeal is lost, you lose PR status and your rights to work or go to school here without a proper visa. So basically you would have to drop your life in Canada and move back home unless you can find some other way to apply for PR independently afterwards.
You will not know for sure if an appeal will be successful until you actually try. Nobody here can say for sure, all we can share is how similar cases have resulted. You can do your own research of past appeals with people in your situation on the Canlii site: *Removed for reporting*
Did he apply for a PR TD? Or did he just simply enter Canada?
