None of these words point to Khalid Khawaja being the CIA agent.
However, after reading the transcript of the conversation (and pointed out by khoji) it is clear that Hamid Mir has direct connection with TTP and nowhere in conversation he questioned TTP’s acts against Pakistan, so by that its easy to conclude that Hamid Mir is TTP supporter. Though it was already clear to me during Lal Masjid saga as well as operation in FATA.
