Both watches look legit at first glance, and comprise a nice inheritance. What else did you get?
The crown/stem issue is probably not a particularly difficult or expensive repair for an experienced watchmaker, I find that it's common for old watches that haven't been serviced in a long time to have winding issues and/or need a new stem. People can guess what's wrong, but the bottom line is that a professional needs to look at it to diagnose the issue. However, if you are going to start doing repairs, you are likely to end up doing a full clean/oil/adjust service, which will cost you something in the 3-digit currency unit range, depending on which continent you reside in.
You should probably decide what you want to do with these watches. Do you want to restore them all for your own use? Do you want to sell them all? Do you want to keep one or two and fix them up for yourself, and sell the rest?
For any that you are going to sell, just describe them to the best of your knowledge (you don't need to be an expert, just be honest about what you know and don't know), take plenty of photos, and put them up for auction on eBay. Don't spend any money on them. If there is one you're sure you want to keep, take it to a good local independent watchmaker once COVID-19 dies down. Since we don't know where you live, you'll want to ask some local collectors for recommendations.
In terms of identification, again we can guess based on looks, but if you can take photos of the inside, showing the movements and the serial numbers on the movement, we will be able to give you much better information.
