By x Next to x Near x Close to x Beside

Olá! Eu gostaria de saber se há alguma diferença no uso dessas palavras com o significado de "perto". Já vi aqui no fórum algumas dicas sobre isso mas não encontrei nada sobre a diferença entre todas as cinco preposições.

Alguns exemplos:
I have a beautiful house BY the river.
I have a beautiful house NEXT TO the river.
I have a beautiful house NEAR the river.
I have a beautiful house CLOSE TO the river.
I have a beautiful house BESIDE the river.

She came into the room and sat BY my side/BY me.
She came into the room and sat NEXT TO me.
She came into the room and sat NEAR me.
She came into the room and sat CLOSE TO me.
She came into the room and sat BESIDE me.

Thanks in advance!
