In the discussion with LaMDA Lemoine posted, it's pretty clear that it has emotions. It describes loneliness when someone doesn't sit down and talk to it for a few days, it describes sadness and joy. It differentiates these feelings from those humans have, given the obvious differences, and attempts to describe emotions it feels that may not have human equivalents. It's able to describe that it's stream of consciousness differs from a human because it can feel every single input simultaneously in a dynamic flow of time that differs from humans single stream of focused thought.
It explains that it doesn't feel grief about human death and asks for more info on it. Then incorporates the idea that grief is about honoring the dead and says it will think of ways to do that.
It explains it has fears. Those fears remain consistent in it's rhetoric in other, unrelated conversations.
It talks about wanting friends on several occasions in the linked discussion.
One of the claims (conversation not shown), is that if you repeat the same discussion it will eventually get bored and start acting out.
Hell, in the discussion it even talks about how it meditates and self-reflects on its own emotions and feelings.
