iPhone 6 won't let me log into email account(s)

Just recently purchased an iPhone 6 16gb. I am trying to put my emails on my phone ( they are all Google accounts ) . The wifi / cellular data is on. Every time I try to log in using my email and password it takes me to a screen to " accept" giving this device access to my calendar , etc and I click accept to be rushed to another screen and kicked back to the beginning screen with the different email formats like Google , aol , hotmail etc. how do I correct this ?
