Your question could be comparable "How much does a car cost". It goes from the cheapies at 6.000€ to Ferraris, Bugattis and rare models going to millions.
Decent lenses start at 200€. 50mm f2 primes are cheap and good, it's the focal length most optimised, since it was the usual kit lens with 35mm SLRs.
As said before, Teles (specially big aperture) and big aperture lenses are what most cost. He missed some types of ultrawide lenses. And zooms that have a non variable aperture.
Big aperture lenses need more complex designs and different glass materials, for keeping good performance wide open. That raises the price.
Lenses can be expensive. They start at about £80 or £90 and can go up to the thousands. The more expensive lenses tend to be fixed (non-zoom) lenses that have long focal lengths (for example, 300mm, 400mm, 500mm etc).
Lenses with large maximum apertures (for example f1.8 and below) are also usually, but not always, expensive. The ones that aren’t are usually great value. Large maximum aperture lenses have advantages.
If you choose a lens with image stabilisation built in, such as some in the Canon and Nikon ranges, again you can expect to shell out.

It all depends on what type of lens you actually want to purchase anywhere from about $100 easily well over $100,000.
