You can pretty much fit any LF lens, however there are a few caveats...
Lens/Shutter. Not all LF lenses come with a shutter attached. You will need one that comes with its own shutter. The standard focal length for 5x4 is 150mm (roughly equivalent to 50mm on a 35mm camera). They can get expensive for modern glass, but the beauty is, you can chuck pre-war glass on there and still get excellent images. I have one lens taken off an old Kodak folding postcard camera - I was most annoyed at how good the lens is: I was hoping for some interesting defects...
Lensboards. The lens needs to be fitted to the correct size lensboard. If I recall, the Camerabellows camera uses a Linhof style board which is a very popular type. If the lens is not fitted to that type of board already, you will need to get one to fit. Do not buy a Linhof brand board - they cost a fortune and are over-kill for your purposes - buy a cheaper no-name one.
A Second point about lensboards is the size of the hole to take the lens. The size of the hole is dictated by the shutter size and are numbered: #0, #1 and #3 are the most common. You just need to order the lens panel with the correct size number for the shutter, or you can make your own out of thin plywood.
Coverage: Some lenses that look like LF lenses are in fact only intended for MF and will not cover the whole 5x4 inch negative, or will do so with little to spare (like my postcard camera lens). Because of the movements available with a view camera, the lenses used normally have a much wider coverage than the size of the negative.
It really is a big subject and a book or two is probably the best next investment...
Have fun, Bob.
