The one on the left appears to be a Super Speed, the next one an Auto Strop? Then you have an Ever Ready or a Gem single edge and last appears to be some sort of open comb travel tech.
Having said that, more pictures showing markings would be helpful.
B&B guidelines prohibit giving values, so only you can decide if it is worth purchasing. The SS is a solid razor and a value is easily determined by checking "Cimpleted Auctions" on eBay.
The handle on the third one from the left looks like it might be a Damascene which is a little more popular in the SE world. The forth one looks like a German 4 piece travel razor, I have one and it shaves very well, like an OLD. Gellette also made one like it. I'm with @BSAGuy on price, if that.
