Yes.
Some drives have a jumper on them you have to close that allows the drive to present the proper SATA version to the BIOS, other times it is simply automatic.

Did you mean if SATA I cables can run SATA III drives? I think yes, but limitting the bandwidth to 1.5GB/s.

If I understand your question correctly, I believe the answer is "no". Each sata drive is independently connected to controllers on (or connected to PCi or PCIe bus) the motherboard. A controller knows how many sata drives are connected to it, and software running on the CPU can determine the total number of sata drives connected.
