I basically agree with the others that it is too early to decide which lenses to keep but you may wish to consider a few points.
The Yongnuo 50mm f/1.8 is a very low cost lens but the reviews seem to think it OK. On the other hand it will focus on the D5600, the Nikon 50mm f/1.8 D will only auto focus on the D7100. Unless you really think you will both need this focal length at the same time I would get rid of the Nikon 50mm. Alternatively replace both with a Nikon 50mm AF-S f1.8, they aren't expensive.
The Tamron 18-270mm f/3.5-6.3 duplicates both the 18-55 and the 18-105 but does give some unduplicated extension from 105-270. Its f6.3 maximum aperture is within the AF range for the D7100 but only when using the centre focus point. I am unsure as to its compatibility with the D5600.
I had an early Sigma 17-50 f2.8 and I was happy with it but ultimately I bought a Nikon 17-55 f2.8 which was a better lens. A used example of the Nikon needn't be terribly expensive. If you buy one you won't need both 18-55 and 18-105. My wife prefers her 16-85 VR to the 17-55 so keeping the 18-105 may be the best option.
We have a standard zoom each and a 70-200 each, we do use the same focal length ranges at the same time so I think you should be looking to a similar arrangement if you both want to use the cameras simultaneously.
Having said that, do as Eric and JK suggest and just use what you have until you have a better idea of how you will use the cameras and what you really want to do.
