Is participle corresponds to "HOW" part of the sentence?

Question

From this (very helpful) video I learned about the basic structure of a sentence.

WHO > WHAT > WHERE > WHEN > HOW > WHY

Now I'm trying to learn about different word orders. Specifically I'm learning participle.

1. Is it correct to think about participle as the HOW part of the sentence?

E.g.

They ran downstairs looking angry.

WHO WHAT WHERE HOW

or

Looking angry they ran downstairs.

HOW WHO WHAT WHERE

2. The teacher from the video said when you switch the word order the sentence might sound unnatural. Does the second example sound unnatural to a native speaker?

Thanks

Answer 1

They ran downstairs looking angry.

and

Looking angry they ran downstairs.
Looking lost, they ran out the door.

Both sentences are fine and understandable.

The sentence might be rewritten

Angrily, they ran downstairs.
