So there is no specific requirement that there be specific number of eligibles? If A brought in 6 lineman, all numbered 50-79, and none were on the end of the line or in the backfield (i.e. only 3 in the backfield, 2 on the end of the line for 5 total eligible), would this be legal?

From my limited understanding of the rule, it would be legal to do as you suggest. Others may correct me if I've missed something in the rulebook.
