You examples have to do with the order of ADJECTIVES in a sentence.  Generally the order goes as follows:

Generally, the adjective order in English is:

1. Quantity or number
2. Quality or opinion
3. Size
4. Age
5. Shape
6. Color
7. Proper adjective (often nationality, other place of origin, or material)
8.  Purpose or qualifier

Order of adverbs

My doubt is when i have 2 or more adverbs of manner together. I don't know the order.

Examples:

"It's the most expensive original exiting designs".

"The was was covered in old ugly black graffiti."

"It's an old boring social documentary".

"I had lunch in a small old cosy café"


Are they right??
