I will attempt to answer your questions to the best of my limited understanding.
1. It's going too far to say that the cases which resulted in fines were fictitious. They were real cases processed in the real courts before real justices.
The difference is that both parties colluded willingly in the process, and everyone involved (including the justices) would have known all along exactly how the matter would end up.
I have recently transcribed documents from around 1505 relating to a fine involving my ancester.
In this case a number of the intermediate deeds and writs survived with the fine. They are all very real.
2. The land is being transferred from the 7 Harrys to John Broade.
As far as I know, the only clue this document provides* to the nature of the transfer (regarding sale/lease) is that they remise and quitclaim from themselves forever. So it probably isn't a lease, because the owner would retain a reversionary interest in leased land.
This doesn't have to do with the copyhold relationship between a manorial tenant and the lord of the manor.
However, if a manor were conveyed from one lord to another by fine, I'm sure the manor court rolls would acknowledge the transfer.
3. I'm not sure what is signified by the warranty against the grantor. In a basic sense the warranty should cover the grantor, but why it is stated explicitly here instead of as part of the contra omnes homines isn't clear.
My instinct is that this is just process, rather than a reflection of previous trouble, but who knows?
4. Correct. Sometimes the date and other brief notes are on the back.
5. Correct, unless I am badly mistaken.
* However I would like to know more about the meaning of the words between Egidio Harrys and de tribus on the top line. There may be a clue in this section, which I can't fully transcribe.
