Bonjour. Comment cça va ? Bonjour. Comment ça va ?

Space before and after : ; ? ! « » % You need a cédille <ç>, otherwise the word would be pronounced /ka/

🙏 🥹Merci de m’aider . Bonjour. Merci de m’aider. Bonjour.

Original, this smiley-sentence mix, I think this is the first time I see it here. Still, I wrote what the sentence would be in plain French

Comment cça va ? Comment ça va ?

Je m’appelle Jay. Je m’appelle Jay.

Je suis de Americaviens des États-Unis 🇺🇸. Je viens des États-Unis 🇺🇸.

"Amérique" to refer solely to the United States is pretty old-fashioned. Most people just say "États-Unis" or "USA" "venir de" would also sound better than "être de"

Je es'apprends/J'étudie l'espagnol et le francçais. J'apprends/J'étudie l'espagnol et le français.

Je+vowel = j' "estudier" would be Middle French (spoken some centuries ago), not modern one, sadly There would be a small nuance of meaning between "étudier" and "apprendre". Acquiring a language to speak it is rather "apprendre" to me, but both can be interchangeable Language names require articles (and they're all masculine) => LE français, LE russe, LE hindi, LE mandarin...

Je traivevaille beaucoup endans une hôpital. Je travaille beaucoup dans un hôpital.

"hôpital" is masculine

J 'habite aà New York. J'habite à New York.

a = has; à = on, at (preposition) Just like in Spanish, accents and diacritics in general are compulsory in French

J’e parle anglaise, espagnol et russe. Je parle anglais, espagnol et russe.

"j'" is only used when the first sound of the following word is a vowel (it's not standard in any other case, although it can be written this way to reflect oral speech)

En lSur LangcCorrect, Je participe en lj'écris des textes. Sur LangCorrect, j'écris des textes.

All websites, apps, softwares etc require the preposition "sur" => SUR LangCorrect, SUR Twitter, SUR Discord... participer À quelque chose "participer aux textes" would sound weird in this context though

Bonne journeée. Bonne journée.
