Practice witting

Running is my favorite sport. I started running since last year. Now I run with my boyfriend almost every day from 6.00 P.M. to 7.00 P.M. We run around the village for 5 (?) round. Approximately 5 KM. We never join the running events. We run for get strongly to strengthen our hearts and good health stay healthy. We decided to attend the a running event in the future. I should practice every day to build self-discipline. I need to challenge myself.

I don't understand what you mean by "round"  in "run around the village for 5 round".  Perhaps you mean "laps" as in "I ran 5 laps around the track"  

I changed "attend the running event" to "attend a running event" because you don't mention any specific event, although both are grammatically correct.

My Dad

Hi, my name is Ngoc.  I'm 17 years old. I live in Vinh city with my family.  My family have has four people: daddy my dad, mommy my mom, my older sister and me.  Daddy My dad is the person I respect the most.  He's 52 years old and kind, generous, creative, hard working...in general, he is a good man. He's good looking too, short black hair, hight (high) straight nose, brown eyes, square face...and he's very tall. My daddy dad is a bank clerk, he works in a at BIDV bank.In particular,daddy my dad plays sports very well. He can play almost any sport such as play volleyball, football, badminton and so on.  Because his job is related (you could also say "relates" instead of "is) to economics so he enjoys reading the newspaper.  Besides Additionally, he likes to drink coffee, take care of children, listen to music and cooking.  Daddy My dad is the person cooking cooks the best in my family, he can cooks everything what anything that I want.  He is very pampered pampering and loving to me and I love my dad very much!

Note your use of "daddy" and "mommy" are correct, however these terms only used by young children.  When talking to your siblings or your mother you can say "dad" but when talking to people outside your family you should say "my dad".

"Pampering" is correct but it sounds strange to say a father pampers his teenage son.

Bestie

I have a girlfriend.  Her name is Khloud . She is 18 years old . She is older than me . She is has been my girlfriend from grade 7 since 7th grade to now . I will describe it her to you . It’s She's more than beautiful . Her length height is 163 cm and her weight is 50 kg (It sounds better to say "She is 163 cm tall and weighs 50 kg"). Her hair is long and her color is black . Her face like sunshine . Her eyes are large and her colors is brown . Her nose are like the a sword (The use of sword here doesn't make sense). Her mouth is very small . She is like an angel . And she is mean means more to me more than a sister. It’s She's my best (friend?) and I am so lucky for having to have her in my life . I love her so much more than she knows . Finally, I hope everyone gets a friend like my girlfriend .

Note, in English we never use "it" to refer to a person.  Doing so is insulting, clearly not what you mean.  Always include the unit such as centimeters, kilograms etc. when describing height and weight.  English speakers don't know what it means for a nose to be like a sword.

I want to a girl friend

Hey pliz ı want to learn English so I need to a girl friend for talking.

"Girl friend" often means a romantic partner.  In your title you may want to say "I want a female friend" so that your meaning is clear.

My best friend

Maitha is my favorite best friend. (Favorite is correct, but it is not normally used to describe a friend)  We complete together 8 years We have known each other 8 years (or "we have been friends for 8 years"), it’s a nice years i enjoy with my friend I have enjoyed these years with my friend (It sounds odd to say this.  This might be better expressed as "I've enjoyed all the time we've spent together"). Before 5 years maitha make for me a Surprises in the bus After 5 years, Maitha gave me a surprise on the bus (I'm not sure what you mean here.  I think you mean that after knowing Maitha 5 years she surprised you be giving you a give while on the bus), she bring for brought me a nice bag and chocolate from Germany. When i came i ask maitha this bag for how she said takes this bag to you i bringet to you from Germany. (I don't understand what you mean here.) Maitha knows i like Germany German things because when i travel to Germany i bring a lot of chocolate from there. My life was happy when i know her (The use of past tense "was" implies you are no longer friends.  "when I know her" doesn't make sense because once you know someone, you always know her) I am happy when I'm with her, because i have a good friendship with her .

That is correct, but the phrase you are more likely to hear is "I mistook you for somebody I used to know."
