How to remove an Instance from Auto Scaling group

Question

Hi, Help needed, for some reason I now have 6 instances running vs 1 previously, which is costing me a lot more money.  I have tried to stop 5 of the instances but as they are part of an Auto Scaling group they have all kicked in again.  I cannot see how to remove the instances from the Auto Scaling group they are part of.  
How do I remove the instances from the Auto Scaling group?
Thanks

I think you have two options. Firstly you can adjust your Auto Scaling Group to have a smaller maximum size. https://docs.aws.amazon.com/autoscaling/ec2/userguide/asg-capacity-limits.html

Alternatively you can remove nodes from the Auto Scaling Group and then terminate them as you wish:

Hi Alex, thanks very much, I did the 2nd option too and have now further reduced my instances down to 2.
