I bought Minecraft PS4 version on my PS4 console years ago, but I don't know which PSN account I had purchased it with. How can I also retrieve that info?
Can I download a PS4 game on a different PS4 system with the same account?

Yes, you can download it, even when you're using a different PS4.
And as for the forgotten ID, first of all, try checking ALL of your known e-mails for the purchase, since PSN were using e-mails as their way to login and they'll send a recipt to it when you bought something.
After you found the e-mail/ID, then you can login straight away, or you can request for a change password if you forgot.
But if you also forgot your E-mail, then I suggest you contact the Playstation Customer Service to resolve it. Don't forget to prepare lots of creditentials, since you need strong evidence for proving that you're the rightfully owner of the ID.
