Can adults use pumpkin pail or a plastic bags to go trick or treating with kids to get some candy,about October 31st.

You can use anything like. I personally still go trick or treating with my boys of course and we use pillow cases they're durable and they hold lots of candy. However you might want to check your local newspapers and social media apps because most trick or treating goes on before Halloween hope you have fun remember bring a flashlight Safety First

Yes you can

I would not let kids go alone use what you wish and be careful
