It seems only two divergent timelines were created: the one with 2014 Thanos traveling to the present day (or future) and the one created by Steve Rogers.
All six "leaks" had been plugged by Cap when he returned all stones to the right temporal coordinates, resulting in the present staying intact.
I believe we more or less have this:
(Not depicted to avoid
Primer effect: Rogers' travel with the stones, Banner and Lang (except for when he returns the stones), the other Avengers travelling with the respective stones, Kelvin Gamora travelling back with Thanos)
Legend:
1944: Rogers falls to sleep.
1970: Stark and Rogers get the Space stone, Rogers returns it.
2011: Both versions of Rogers awaken
2012: Rogers, Lang and Stark retrieve the Mind and Time stone, and Thor's hammer; Rogers returns Mind and Time stone and Thor's hammer; Loki steals Space stone, which alters the timeline.
2013: Rocket and Thor retrieve Reality Stone dust, and Rogers returns Reality Stone no longer dust, which also alters the timeline (don't remember what happened with Jane Foster any longer)
2014: Guy Who Should Be Dead and Romanoff retrieve Soul Stone, Rogers returns it; Nebula and Rhodes retrieve Power Stone; Rogers returns it, Quill takes it again; Alt Thanos leaves that timeline to die in the other one.
