Denis,
I have a Mamiya RZ67 which is about the same as you have and have a bunch of lenses for it. I assume you are shooting it as a 6x7 format. For normal shooting the 90 or a 110 is pretty much the standard lens, the equivalent of a 50mm lens on a 35mm camera. It is a good general purpose lens.
Take a look at a 50mm lens if you want something a bit wider. You can get a good near far perspective with a 50mm lens. Going the other way, you might want to look at something in the range of 140mm as a short telephoto or portrait lens or a 250mm if you want something a bit longer to capture those far away landscapes.
There are all sorts of lenses in between those mentioned but if you get a 50, 90, and 140-250 you should have everything covered for normal shooting.
