Q: Migration assistant help needed please, moving from a pc to a mac

If all you need to transfer are documents created by applications, then it may be a lot easier and faster. to simply copy the documents you want to an external USB drive. Then connect that drive to your Mac and recopy the files from the drive to your Mac.

Migration Assistant is always iffy and slow between PCs and Macs.

Migration Assistant will simply create a new user account on the Mac for you to log into. It will replace the user account you are now using on the Mac.

Application documents usually are stored in the /Home/Documents/ folder on the Mac. The "Home" refers to your user account that appears as a folder with a House icon on it. It's actually located  in the /Users/ folder of the hard drive's startup volume.

No. You would make it your permanent account and delete the one you are now using. If you have anything in your current account, then you would need to move it to the migrated account (or you can do it vice-versa.)

I wouldn't think there is anything you need from the PC other than your documents, however.

Much simpler with a drive, but you can try connecting both to your local home network, enabling File Sharing on the both computers then transferring files over the network connection. But then that's what you were doing using Migration Assistant.

You mean between the two computers (ad-hoc type network) or each computer connected to your local network by Ethernet cable (this is how it should have been unless you don't have a local home network with router.)

Either way can work. However, you need to be sure you actually have established the ad-hoc network between the two computers if you use direct connect. If you use the local network method, then you must be sure you have File Sharing working between the two computers. If the computers are not properly talking to each other, then Migration Assistant won't work nor will any other basic attempt to transfer data.
