Yeah. Just off the first movie I believe there are 3 time lines. I could be wrong though.

There’s halloween 1, 2, 4, and 5 Then there’s halloween 1, 2, H20 and resurrection Then there’s halloween 1, Halloween 2018, Halloween kills and Halloween ends.

Then there’s also the Rob zombie Halloweens, but those are completely separate. There’s also halloween 3 but I’m not sure where that fits in since it didn’t have Michael Myers.
