Importing blogs from HubSpot to WordPress

I previous created about a year’s worth of blogs on the HubSpot platform, and I would now like to import these blogs into a new WordPress blog at:

https://navocate.com/content

(Nothing there at the moment, however.)

I exported all of the HubSpot platform blog content consisting of HTML code for each blog, as well as all of the images.

Questions:

1. Can someone suggest a process or sequence to import this data into my WordPress site?

2. Is it possible to retain the original blog dates and posting sequence? Or will the dates get overwritten during upload?

3. I will need to edit the blog links after import, given that all of the links are now obsolete. Presumably I can just do that from the edit menu after the import has been completed.

3. Any other questions or issues I should be aware of, but am not asking now?

Thanks.
