Hi. Let say I have 30 feet movement speed, can I walk 10 feet, jump of a cliff, have the wizard cast feather fall on me, fall 60 feet and then move 20 feet? The alternative would obviously be to say that the 60 feet count as my movement. If I read the rules right, the first interpretation is right.

For a rogue this can make for some really crazy fast escaping if my rules interpretation is right.

Based on the wording of Feather Fall, I feel like the 60 feet of falling would take the entire round. If you were only falling 50 feet, then there is an argument to be made for moving, falling, then using up the rest of your movement. The wild part is when the wizard walks 15 feet off the edge of a cliff, casts Feather Fall on himself, casts Fireball on the enemies below him, falls 50 feet, lands, and walks another 15 feet like a boss over the crispy corpses of his fallen enemies.

You are correct. And the rogue can dash twice, I've had a level 2 rogue run 120 feet per turn before.

I think this is only 90' unless the rogues base movement was 40'.

You get 30'.

Use dash as your bonus action and you get another 30'

Use dash as your action and get another 30'

You don't double your base movement for each dash you just add it.

Haste. There

 The rogue in question was a swiftstride shifter, who used the previous turn to shift, making base speed 40. The same campaign has a tabaxi ranger who has also dashed 120 feet in a turn.
