the question was if you can use 5 V pin as gpio. (I know, it is hard to understand how can someone ask it)

Your comment is the only one I've found so far searching that states the LoLin NodeMCU has power on VV instead of Vin. I'm seeing that as well. Doesn't follow the NodeMCU spec. Although I agree with other comments that this doesn't necessarily relate to this question.
