From these miners, is there a difference in hash-rate with the same hardware, if so what is it for your hardware?
- Wolf's CPUMiner - Open-source
- YAM Miner - Dev fee, Closed-source
- Claymore's CPU Miner - Dev fee, Closed-source
I think this question misunderstands how miners work. Within the ones you listed, they each have a different purpose.
Wolf's CPUMiner, YAM Miner, and Claymore's CPU Miner are all meant for CPU. Some work on more operating systems than others.
Wolf's GPU miner and Claymore's GPU miner are both meant for AMD GPUs. Wolf's is open-source, and Claymore charges a mining fee but is sometimes a little bit faster.
All the ones you mentioned are about the same difficulty to use. The Monero Spelunker is the easiest to use CPU miner for Windows.
Performance for each will vary significantly depending on what cards/chips you have.
For a good start, check out the the Wiki on /r/MoneroMining. It doesn't have information for all the miners you had listed (yet), but it should help you understanding mining a little bit more.
