comment how to apply Alternatives command to delete cases from a list?
A minor variant DeleteCases[newD, # | Reverse[#, {2}] , {2}] &@ (Alternatives @@ listF). To delete just one element from each sublist, maybe: Function[x, DeleteCases[x, # | Reverse[#, {2}] , {1}, 1] &@ (Alternatives @@ listF)] /@ newD

comment How to generate a limited number of tuples of a list and not all?
@Marilla Thanks for your kind comment. To get the tuples 10 to 20, say, where n =10 could be done as follows: IntegerDigits[#, 2, 10] &@Range[10, 20]. I have updated my answer. Note there is no longer a requirement for Map! I also agree with you that Bill's answer is better (and no doubt faster). I did it the 'lazy' way, as I don't like the 'i's and 'j's.

comment how to find sum of variable c1+c2+c3 for expression combinations
Maybe you require Reduce? Reduce[{a1 + a2 + a3 + b1 + b2 + b3 + c1 + c2 + c3 == 45 && a1 + a2 == 10 && b1 + b2 == 3 && a3 + b3 == 14}][[1]] gives c1 == 18 - c2 - c3
