Can people with autism hang out with people a lot?

Yes, autistic people can have out with people a lot.

For many autistic people being around other people can be a challenge, both because they struggle with social ques and communication, however many autistic people not only can hang out with people but also actively look to hang out with people as much as possible - because autistic doesn't make someone anti-social. You may find that autistic people need to take a 'time out' from other people sometimes to avoid being overwhelmed, for example the autistic person may hang back from the group, or step outside to calm down or distract themselves with their mobile phone.
