Creating animation

I am currently using blender (but it is seriously making me mad) so I figured I should try to animate a little in unreal engine.

I dont even know where to start… as for questions

1.) how do I get to the animation editor
2.) where can I create animations in unreal
3.) How can I make a hitbox on the animation?
4.) how do I link the animation with a button
5.) how do I link the animation with a widget (as in making it drain stamina or health)

Thanks as always, you guys are awesome!
