I think 5 lenses would be great. Right now we have seen from Apple and Samsung telephoto lenses which are great. And from LG a wide angle lens which is fantastic. But its always nice to have a regular camera with a small large aperture for great low light shots. So thats your main 3 cameras right there. Although I rarely use front facing cameras I think for many people who do, the benefit of having a wide angle for group shots and a regular one with high detail/low light would be great. I just hope it doesn't drive the price up much. My contract is up November 2019 and i'm on the top rate so should be able to upgrade to any flagship I want. So if the S10 comes out sometime in 2019 it will have a few months to iron out the bugs and potential exploding batteries before I can get my hands on one. Should be perfect. Right now i'm happy with my V30.
