Technically when Azazel said that, he was using that as an excuse to help Sirzechs.

If Ise rescuing Rias not only fails but gets exposed, then the Devils won't be pleased since they were attack by the Khaos Brigade, so if Sirzechs or any of the Maous make an exception and allow Ise to meet Vali in order to rescue Rias, discontent Devil will appear.

So to solve that, Azazel gave out the suggestion to say Ise and the others became Fallen Angels, that way the Maous won't be blame, and Azazel will take in all the sins.

Did you forget they can sense each other through ki. If Koneko's ki directs her ki to Kuroka, do you think Kuroka wouldn't come? Especially when she's quite a sis-con herself.

Regarding the feelings thing on the Dimensional Gap, maybe it applies both ways, plus Rias was being manipulated so her mind was blank so it might have allowed her to easily summoned. Lots of explanations.
