Hello Alvinimi and Welcome to MySwissAlps,
The Saver Day Pass will cover you as far as Mürren but you will need to pay full fare from Mürren to Schilthorn unless you also have a Swiss Half Fare Card.
All the other trips you list are fully covered by the Saver Day Pass.

Hi Alvin,
Note there isn’t an Interlaken lake. Interlaken is situated between Lake Brienz and Lake Thun (both are covered).
You can see the coverage area of the Saver Day Pass here: https://www.myswissalp s.com/onedaytravelpass /details – click the link under “more on other websites”

Very pleasant walk between the two lakes at Interlaken.
About 30 minutes as I recall; a leisurely stroll along a wide footpath.
You can take the train (one station) and possibly a bus.
Enjoy your travels.
