Yes you can apply together, so you dont need to sponsor them. You can be the main applicant and other family members will be dependent. Just check in NOC that if your job profile comes in the category. I believe you are eligible to apply. And it will roughly take around 1year.
Oh GOD.... if you are not sure, you can say "I guess" or "I am not sure"
You are passing WRONG information so confidently that who are new to system would believe you.
What you have said is not possible & is totally wrong.
1. S/he may be eligible, if his/her job category is under NOC 29 list.
2. It may take 12-20 months to get PR to him, if all required docs are submitted.
3. Once s/he land, find a job, have minimum required income, can sponsor his/her parents, that takes 5 to 8 years in total.
3+ yrs. application remains in Canada, 4+ years time it takes in country of his/her parents residence.
Applicant can not add parents in his/her application, applicant only add spouse & kids (or may be minor dependents, in some cases - I don't have that info) in his/her application.
