OK, first you have to narrow it down to what you need and what type of camera you have.
Your 35-70 will be great for all occasions, very flexible and wide range of uses (nature, landscape, wide shots)
The 35mm f2.0d will come into play when you have low light situations. The 2.0 is the how fast, or how much light the lens allows in. The lower the number, the better (and more expensive) the lens. This is great for portraits and low light situations.
Forget the 3rd lens.
If you have a Digital SLR, then you will need to find out the multiplier for equivalent focal length in film. Since a full frame of 35mm SLR is different from a traditional DSLR sensor, you need to multiply the focal length to see what it would actually equal if it were on a film camera.
For example, my Nikon D40 has a multiplier of 1.5. So if I place a 50mm lens on it, it will equal the same as a 75mm (50x1.5) on a film shot.

35-70 is a zoom lens. Most likely the lens that came with the camera. Its useful for most general photography, although limited on both ends of the zoom and not very "fast".
the 35 prime, that is actually a nice lens. 35mm is the "normal" lens of digital cameras (52.5 with the 1.5x crop factor.). 2.0 is pretty fast. This is also a good general purpose lens and what you should be using to learn on.
the 28 is also a prime lens, similar to the 35, but not as fast and wider. it is better for nature/landscape shots. but for a 28, its pretty slow. on a digital camera, it would be of for general every day photography.
For wedding photography you should get something between 85 and 135 mm and pretty fast, 1.7, 2.4 something in that range. Also you would need some really good flash. For just taking pictures of the bride and groom at the reception, the 35-70 is fine, but see below about the 28-300...you will appreaciate the zoom!!!
For landscapes, get a 17-35, or just use your 28. For fields, trees, mountans that is fine. For sunsets, I took most of mine with a 28-300 zoom, but have also used my 24 1.7. The trick with sunsets is not the lens, its learning proper metering. First focus and compose the picture with the sun setting. Then move your camera so the sun is just to the left of the frame, but off camera. Take a meter reading and remember it. Then do the same on the right. Average the two readings and use that as your settings. Then take the picture with with the setting sun in frame. Viola, perfect metered sunset (or sunrise) pictures.
For portraits, again, 85-135 is the way to go. For just normal family evreyday portraits, the 35-70 will be ok.
everyday phot, your 35-70 is fine, or get a 28-300 sigma or tamron hyperzoom. Great vacation lens, not to fast, but pretty sharp pictures and pretty light.
Hope that helped.
Don't bother getting hte D80. From your question, you don't know enough about photography to justify the added expense. The D50 is a fine camera and you should learn on that before spending money on a new body that I bet you do not know the difference in the features to use them.

If these are for a 35 mm film camera or an FF DSLR camera. They are all moderate wide angle to normal lenses. If they are for a crop DSLR, that is a digital camera that has a sensor smaller than a full frame 35mm negative they are standard to moderate tele. The will be good for all things you mentioned, as you get some experience you will know what you need, wider angle lenses, telephoto lenses, macro lenses etc. If you tell us what camera the lenses are for we can give more specific information.
