Today, I found out an interesting English sentence while I was in English class.

The sentence was written on English conversation, I got surprised a little because I thought someone may have been stalking me.

The sentence was written on English conversation,(./;) I got surprised a little because I thought someone may have been stalking me.

For this sentence, a comma cannot be used here because there are independent clauses (full sentences consisting of both a subject and a verb) on both sides of the punctuation. When you want to combine two full sentences into a single thought you need to use a semi colon (;). Otherwise, use a period to separate full sentences. This is very difficult for many English speakers as well though, so don't worry about it too much!

I'm actually trying to learn English conversation. lol

I'm actually trying to learn English conversation skills.

I'm actually trying to learn how to have English conversations.

Your original sentence does make sense, but adding "skills" sounds a bit more natural to me and clarifies the meaning some. I've added a second option you could use as well.

Well, the author of that sentence insisted that English conversation should be learned through actual experience - to practice, not by reading how-to books.

I totally agree with the author's opinion.

Most of Japanese who want to learn English conversation have less chance of using English in real life.

Most of the Japanese people who want to learn English conversation have less little chance of using English in real life.

Most of the Japanese people who want to learn English conversation have less few chances of to using use English in real life.

In this situation, "less" will be understood but is not grammatically correct. "Less" implies comparison whereas "little" and "few" are more descriptive. The difference between these two words is very subtle but the grammar surrounding them is slightly different. Personally, I feel like the first option sounds a bit more proper, but the second option is possibly more likely to be used.

I'm in it too.

I'm in it this situation too.

This sentence needs to be more clear to make sense to a listener in English. Using "this situation" links the sentence to the situation you described in the previous sentence.

We don't even see English advertisement or whatever written in English on the street, TV...

We don't even see English advertisements or whatever written in English on the street, or on TV...

That's why I decided to use this website to have more experiences and practices.

That's why I decided to use this website to have more experiences and get more practices.

That's why I decided to use this website to have get more experiences and practices.

Either of the above options work well here, but which one you want to use will depend greatly on your intended meaning. "To have experiences" and "to get experience" differ in meaning so this one is your choice. Although, in English it is more common that we "get practice" rather than "have practice" (in this situation at least, you can "have practice" for sports and such).

うーん、だからといって街並みが英語だらけになればいいというわけでもない気がするんですよね。
やっぱり僕も日本人だし、母国語の美しさだって誇りに思っています。
英語を学びたい、と思っている日本人はやはり自発的に動いて日ごろから積極的に英語に携わる、といった姿勢が大事なんじゃないでしょうか。
恋愛でもそうですよね。やっぱり自分から動かないと。（何故だろう、この言葉がすごく心に突き刺さるのは……。）

Kaz, your English is very good! Your mistakes are very small so I don't believe anyone would have trouble understanding you at all! Also, I too agree with this sentence that you found. I'm also in the same situation as you, but with my Japanese learning. There is no Japanese on American streets or on the TV either. It is very difficult to get daily practice! Keep up the good work! がんばって！あなたの英語はすごい上手！
