Djembe 1 sounds more like 12/8 than 4/4 to me: I hear it as t|ss.|s.t|s.B|s.(t)|(ss.)
with the first t as an upbeat.
Djembe 3 is written as 12/8, but I think it’s played like a hemiola (1,2&,3; 1,2&,3),
or |B.|tt|s.|B.|tt|s.|
Djembe 1 is hard to learn from the video, it would help to add a section
with the rhythm broken into smaller chunks.
It would be nice to write down the musicians associated with each Djembe part in the first paragraph.
