Can anyone identify these *possible* bug bites?

Im a 13 year old. A few days ago my room had 2 stinkbugs and 3 lightning bugs. I got rid of them and did not sleep in that room for 2 days. There were also I guess gnats or really tiny bugs by my light. Which to mention is right next to my bed and my bed is also under the window. Anyways Heres some of the bites
