Ah! Welcome to the messy thing that is the DC Universe continuity. Yes, there are several Superman timelines, but officially the only 'real' one in comics right now is 2).
1) appears to be an alternate story. Fashion!Lana is from the Animated Series, IIRC, and the reporter/newscaster was the Earth 1 Pre-Crisis Version of Lana Lang (the 'real' continuity before 1985). 5) is from the alternate story "Whatever Happened to the Man of Tomorrow", a must read for Superman buffs.
Yes, the DC continuity is a complete mess. DC fixed it in mid 80's, just to screw it again recently. Superman's continuity in comics is in fact being retroactively being modified right now, thanks in no small part to a TV series called "Smallville". For example, Superman's costume and shield were made by Martha Kent in modern continuity, but from this month on, Clark Kent found the costume when he was young. Comics can get very very messy.
