What is the difference O-300-A / O-300-C / O-300-D?
Can they use the same: mount, starter, generator, mags, carburator, prop, oil filter adaptor, plugs, etc.?

No
300-A has a 8 bolt crank C and D a 6 bolt so the props can't be the same nor the spinner unless your using the skull cap spinner and even that you might want the smaller one for the 6 bolt crank.
300-A uses a straight starter same as the C but the D is an angle starter and different.
Everything else you mentioned is interchangeable.

From the TCM Ovhl Manual:
The significant differences between the 0-300 models are as follows:
A. The 0-300-A engine has a SAE No. 3 flanged propeller shaft and provisions for a starter, generator, voltage regulator and fuel pump.
B. The 0-300-B engine is identical to the 0-300-A except for provisions for use of a manually controlled hydraulic propeller.
C. The 0-300-C engine is identical to the 0-300-A except for ARP 502 Type I flanged propeller shaft and Slick Electro Inc., Magnetos. Information regarding maintenance, overhaul or adjustment of these magnetos may be obtained from Slick Magneto Inc. , Rockford, Illinois. All 0-300-C engines subsequent to serial No. 21001 are so equipped that a right angle starter drive can be used if desired.
D. The 0-300-D engine is identical to the 0-300-C except that the starter is mounted on an adapter which provides a right angle drive.
E. The 0-300-E engine is similar to the 0-300-D except for incorporation of governor drive pad and crankshaft provisions to supply governor oil to the propeller.
