How many kids flunk 6 grade for failing physical education?

There's no reliable data on how many 6th graders flunk (or fail) 6th grade specifically for failing physical education. Many schools don't fail students solely for a PE grade; instead, PE is often a contributing factor to overall academic standing. A failing grade in PE might necessitate summer school or remediation, but rarely leads to grade retention on its own. The number would also vary wildly depending on the school, district, and even the individual teacher's grading policies.
