Running in circles on the top of the cage is a sign of stress and is common in newly acquired rescues.
The other things you list are common of rescues that have had limited experiences with out of cage time and with proper enrichment. Give him time and go slow and he will likely learn all of these things--- same as many rescues have to learn to use a wheel or to play with toys.
Aggression is also common in rescues and is even more common in gliders with some health issues. Have they all had a full wellness exam, including testing?
