Yes: If you had a stress fracture, that means a certain bone in the foot is taking too much repetitive impact. You can definitely damage the same bone a second time. You should wear proper shoes and have gel inserts in them. Definitely follow-up with your foot doctor this week.

Yes: Stress fractures can become full fractures if activity level is not modified or your medical history predisposes you to fracture. Hope that answers your question.

Yes: Yes can return. Get a new x-ray. Check for osteoporosis with pcp.

Yes: But the fracture may never have totally healed. See a podiatrist.
