How to translate Japanese short messages sent by others?

I have already turned it over in another post. ...

What a sweet enjoyment ... I don't quite understand that sentence, but the sweetness in Japanese has childish meaning and may be interpreted as derogatory, so the landlord should use it with caution.

はふゆひとさんのがきです. On "にガタのよ" No, no, no, no, no, no, no. もちろん, これはふゆひとさんのをはさ.

このはきてぃくさにぇられなくなっは. ぁぇることができなきなななぁのちを𞇆. ずっと⾑をしげよぅとってぃました.そのために, はらなくちゃ.

それでは, ぉを, ぉに!
