Is it possible that a friend changed her number and didn’t tell me?

She has responded to my texts and I compared the number she has on her Instagram and it is different

Seriously, if you can still get in contact with her, and she did give you her new number that was associated with the text she sent you... You really can't say that changed her number and did not tell you. More than likely it is possible that she thought you could figure that one on your own.
