What types of similes metaphors personification and onomatopoeia can I use for a scene at a fun fair ?

Similes are a comparison using 'like' or 'as'.

E.g. 'The clown was like a madmen'

'The clown was as insane as a madman'

Metaphors are comparisons without 'like or 'as'

E.g 'The clown was a madman'

Personification is the addition of human-like traits to non-living things.

E.g. 'The circus tent danced with excitement as the show began'

Onomatopoeia is a word describing the sound it makes.

E.g. 'Honk'

'Buzz'

'Ring Ring'

'Woof Woof'
