I don't think any of those are material to you being a sponsor or citizenship app. Misrepresentation is putting materially wrong information,ie that would make them look at your app differently if you told the truth. Mistakes like above are not (in my view).
Keep a record of what info you provided and ask in the citizenship forum when the time comes.
You can always provide a letter of explanation about these things though I think.
One small additional point: I don't think IRCC is out trying to catch people out for just mistakes or typos.
BUT: all applicants/sponsors should still try very hard to be accurate and careful and complete in providing information. (Remember, material omissions can still be misrepresentation).
When IRCC reviews files, the more little mistakes and inconsistencies and oddities are evident, then the lower the credibility is. And that can lead to more reviews and concerns about whether the applicant/sponsor is being truthful about important things.
An example of importance is for those later applying for renewal of PR card or citizenship, where physical days-in-Canada is critical, the credibility of how one keeps and presents records to show one met the residency obligation matters. "Forgetting" a single day trip across the border may not be a big deal; presenting a table of days-in-Canada that has a bunch of errors and has gaps probably will lead to more scrutiny and no benefit-of-doubt.
That doesn't mean everyone needs to freak out and withdraw their apps because of a mistake or typo. Just that it is in your interests to be as accurate as reasonable.
