Red - Hard to say with 100% accuracy, but with just your markings I would say all are made by KEMET. The 476 6K and 475 10K are KEMET T396 Tantalum capacitors.
Based on the marking info. only the K8U 105M, K5K 104, and K1K 103 are also made by KEMET, but are not Tantalum capacitors. They are ceramic radial capacitors similar to this one.
