Is its possible to execute an aggregation query on an index and use the results in one action to enrich the same index/documents with it.

Assume i have serveral document with field region, sensor type sensor. I want to add to each document the number of times the sensor triggered, the number of times it was a certain sensor type and how many times it happend in a region. The aggregation of counting the values are in time frames of 5min.

It's looking a bit similar to what downsampling does: Downsampling a time series data stream | Elasticsearch Guide [8.14] | Elastic

But to answer your exact question, no I don't think you can inside Elasticsearch do that automatically. But you can write a piece of code which does that I guess. Or look at downsampling to see if it helps.
