There are many theories as to who, if anyone, the legend of Robin Hood might be based upon. Ideas range from Robin being an entirely fictional creation, to his being based upon mythology, several different people, or just one person. Since it is unknown who the person or people may be, of course it is difficult to suggest his 'real' name.
However, some historians have attempted to identify possible 'original' Robins, the most detailed and serious attempt being by Professor J. C. Holt in his book Robin Hood (2nd Ed., 1989). Given the complexity of the problem, I would recommend you read the book itself, but in brief answer to your question, it seems fairly likely that the chap's real name was Robin Hood - possibly connected to the Yorkshire Hood family who owned land at that time. Robin being short for Robert, that may have appeared in any number of spellings (since in the time in question - some time before 1262 - spelling had not yet been standardised), for instance Robert Hode, Robyn Hud, Rob Hod, etc. Personally, I rather like the archaic spelling 'Robyn Hode'.
It seems the name was later a nickname for robbers, and so it is possible that it began as a nickname. If this is the case, there is no way to tell the original's real name, since no records have been found to indicate this. Surnames were not fixed in early Mediaeval England, and so it could be that he was known by more than one name - many in those days were known by their place of origin. However, it is even uncertain as to where Robin Hood was based, and so we can only scour the early ballads to search for possible placenames - some possibilities would be:
Perhaps we will never know, although it is always faintly possible that some ancient government record of the outlaw will be found in a library, collection or archive somewhere.
