Bob is right. Table 220.12 gives the minimum allowance for lighting loads in various types of facilities. But for industrial facilities, not being given a separate demand factor in Table 220.42, we have to count 100% of that lighting load. Table 220.44 gives a demand factor of 50% for any receptacle load over 10KVA (and a 100% factor for that first 10KVA). You are right in saying that the NEC does not give demand factors for the other loads in your list. So you must use 100% of such loads.
So the answer is that the calculation is invalid. If I were the one reviewing the calculation, I would send it back as “rejected,” with the simple comment that none of the demand factors comply with NEC requirements.
And by the way, "demand factor" and "diversity factor" are vastly different concepts. The term applicable to your question is "demand factor."
