Today was the eighth day of my English challenge.

You could write here 'the eighth day' or just 'day 8'.

I woke up at five o'clock am.

Here you can either write five o'clock, or you can just put 5am.

Then, I learnt how to use application Canva.

I learn is present tense, I learnt is past tense.
How to use, like, how to write, how to sing, etc.

In the afternoon, I read some English corrections ion the site.

On the website, rather than in. It is confusing. You go ON the internet, ON the website, you talk ON the phone. :)

Then, I decided to use some words in thea sentence which I learnt yesterday.

In a sentence, because it is not a specific sentence.
Past tense of I learn, I learnt.

Here are some wordphrases: To turn on, to chat, to be positive, to huang, to quit, to googele, I feel like+ving, to come over.

They are words, but to be more specific, you can say phrases.
To hang. I hung (a picture) is past tense.
Googel -> Google
'I feel like +ving'. Do you mean - verb + ing? Having, Singing, Doing? This is correct.

I am always postive, so I will improve my English.

Excellent!!

I can't wait to meet my friend at the aeirport.

Airport. This is a word called Aerospace. It is confusing.

I feel like hanging out with him for a while.

Oh dear!! 'I feel like hanging him' means something very different from 'I feel like hanging out with him'!
Hanging out, means to spend time with someone. Hanging him, means to kill him!
Funny mistake, haha.

I can't wait to meet my friend at the aeirport.

I want to hang out with him for a long time.

Today was the eighth day of my English challenge.

I woke up at five o'clock am.

Short sentence

I reviewed some English lessons.

Short sentence

Then, I learned how to use an application called Canva.

If you want to use a comma, use it to combine this corrected sentence with the previous one.

In the afternoon, I read some English corrections ion the is website.

Using 'on' as your preposition here sounds more natural here.

You should be more specific about what you mean by your expression `on the site`. As it stands right now this expression is too
ambiguous to feel natural. You can use `on a website` if you desire the expression to remain ambiguous as to which website you were reading the corrections on. In the case that your intended meaning was literally this website, langcorrect.com, then `on this website` will do.

Then, I decided to use some words in thea sentence, words which I had learned yesterday.

Without this correction it is hard for the reader to understand what exactly it is that you learned yesterday. The original sentence you wrote could be read to mean "I learned some words from a sentence yesterday and then I used those words".

Here are some wordexpressions: To turn on, to chat, to be positive, to become hung, to quit, to googele, I feel like+ving, to come over.

The way you have listed them these are not really words, at least in the general sense.

I am always positive, so I will improve my English.

My style preference is for less usage of commas but I'm sure other people's opinions may differ.

I am positive, so I will work very hard to start my own business.

I am going to come home in a five minutes.

I can't wait to meet my friend at the aeirport.

I feel like hanging with him for a while.

The phrase "hanging him" literally means to try and kill the person with rope, not at all what you intended I'm sure.

I can't wait to meet my friend at the aeirport.

I want to hang with him for a long time.

Another usage of `hang` without a preposition, don't do this because it means you want to kill the person.

I am chatting towith a friend over Skype.

I woke up at five o'clock amAM.

Note, depending on the context, simply "o'clock", "AM", or just the number by itself will be okay.

Then, I learned how use an application called Canva.

Then, I decided to use some words in the sentencemake sentences with some words which I learned yesterday.

Here are some words: To turn on, to chat, to be positive, to huang, to quit, to googele, I feel like+ving, to come over.

I am always positive, so I will improve my English.

I am going to combe home in a five minutes.

sShe lives nearby.

I can't wait to meet my friend at the aeirport.

I feel like hanging out with him for a while.

"Hang someone" means kill them with a rope.

I can't wait to meet my friend at the aeirport.

I want to hang out with him for a long time.

Same as before

English Challenge, Day 08

It's good to be specific about a challenge or contest or something like that.

I woke up at five o'clock am.

Don't need "am" since the reader assumes that you're talking about am.

Then, I learn how usto use the application Canva.

In the afternoon, I read some English corrections ion theis site.

If you're talking about LangCorrect here, then use "this site" instead of the site. It's more specific.

Then, I decided to use some words infrom the sentence which I learn yesterday.

Use "from" here because you're taking the words that you learned a day before.

Here are some words: To turn on, to chat, to be positive, to hung, to quit, to googele, I feel like+ving, to come over.

I am positive, so I will work very hard to start my own business.

I am going to come home in a five minutes.

I want to hang out with him for a long time.

Hanging is a method of dying. "I want to hang him" sounds like you want to kill this person, which I'm sure you don't want 😅. "I want to hang OUT with him" sounds much better.
