I've Office 2007 Home Ed. and Office 97 Profess. with Office 2000 upgrade. Can I install MS Access from 1997?

Yes, no problem because they are all separate programs after all and you havent got any copy of Access on in the Home edition of 2007 which could conflict. I have pro versions of 2007, 2003 and 2002 on the same computers though have installed them into separate subfolders within the programs folder and then actually named them Word 2002, Word 2003, Word 2007 etc so I don't get muddled..
