Answer 1

libc6:i386 is the i386 version of libc for i386 architecture kernels/systems. This is for running packages built for i386 systems and would be required if you are trying to use i386 packages on an amd64 system. This is called multiarch.

libc6-i386 is the 32bit development package of libc for amd64 systems. This is not for running software, its for compiling and linking 32 bit code.
