J3 Cub pilot reported a near miss with two other aircraft while on runway after landing at a non-towered airport. The pilot had safety concerns regarding the other aircraft formation flying and performing a low pass during an airport event.

Narrative

While flying to ZZZ; I experienced the following hazardous behavior from other pilots. After filling up fuel and departing ZZZ1; I began monitoring ZZZ CTAF. When I was approximately 3 miles from the airport; I heard a flight of two report that they were on downwind to runway XX and were going to do a low pass. There were multiple other aircraft in the pattern as well.A few minutes later; I entered the downwind to runway XX from a 45-degree angle and announced my position on CTAF. As I turned base and announced my position again; I could see two aircraft approaching abeam the threshold on downwind. On the CTAF; someone said; 'Are we doing it again?' Another pilot responded; 'Yeah; we need to get lower.' I turned final and announced my position again. I do not believe they made another radio call. As I touched down I saw one aircraft pass me on my left at about 100 AGL and another aircraft on my right at about the same distance and altitude.On my roll-out; there were several aircraft waiting to depart plus families with small children looking over aircraft next to the taxiway. I said; 'Good thing I didn't need to go around; gentlemen.' Another voice replied that I am unsure if it was the other two pilots: 'They meant to do that.' This hazardous behavior left me zero outs if someone had entered the runway to depart or a child had run out to the runway.
