朋 is a simple way to say friend, companion, comrade, or pal in Chinese, Japanese Kanji, or old Korean Hanja.

朋 is a very short form, so a longer two-character word for friendship might be better.

Note: In Japanese, this can also be the female given name, Yukari.

鵬程萬里 is an ancient Chinese proverb used in modern times to wish someone a long and successful career.

It's really about the 10,000 Flight of the Peng (Peng, also known as Roc is a mythical fish that can turn into a bird and take flight).

莊子
Zhuangzi or Chuang Tzu

Breaking down each character:
1. Peng or Roc (a kind of bird).
2. Journey (in this case, a flight).
3. 10,000 (Ten Thousand).
4. Li is a unit of distance often referred to as a “Chinese Mile,” though the real distance is about half a kilometer.

Direct Translation: “Peng's Journey [of] 10,000 Li.”
Literal meaning: “The 10,000-Li Flying Range Of The Roc.”
Perceived meaning: “To have a bright future” or “To go far.”

This proverb/idiom comes from the book of Zhuangzi or Chuang Tzu. It tells the tale of a huge fish that could turn into a gigantic bird. This bird was called a “peng” and was many miles long. This legendary size allowed the Peng to fly from the Northern Sea to the Southern Sea in a single bound.

Wishing someone “a Peng's Journey of 10,000 Li” will imply that they can travel far without stopping and will have great success, a long career, and a prosperous future.

This is the Chinese name for the country of Gabon.

夠朋友 is a colloquial title in Chinese meaning “to be a true friend.”

親朋好友 is a Chinese title that simply means “family and friends” or “kith and kin.”

If you read each character more literally, it's like, “relatives, friends, [and] good/close friends.”

永遠的朋友 means friends that are eternal or a friendship that will last forever - you will remain the best of friends as long as you live.

The first two characters mean forever, eternal, eternity, perpetuity, immortality, and/or permanence.

The middle character links the words (it's a possessive article).

The last two characters represent friendship, or simply “friends.”

不磕不碰骨頭不硬 is a Chinese proverb that literally translates as: Without being knocked around a bit, [one's] bones won't become hard.

Figuratively, this means: One can't become strong without first being tempered by “hard knocks.”

While true for everyone, this sounds like the “Iron Body” form of Kung Fu, where practitioners' bodies are beaten (and often bone fractured) in order to become stronger.
For the rest of us, this is just about how we can be tempered and build character through the hardships in our lives.

This is not a common title for a wall scroll in China.

国家忠诚父母孝道朋友有信杀生有择临战无退 are the five codes of Tang Soo Do.

I suggest you have this arranged in five columns when you get to the options page for your custom calligraphy wall scroll.

Here are my translations of each of the five codes:
國家忠誠 Be loyal to your country.
父母孝道 In regards to parents, behave in a filial way.
朋友有信 Be faithful in friendship.
殺生有擇 When fighting for life and death, make noble choices.
臨戰無退 No retreat in battle.

Note: “Tang Soo Do” is a romanization of 唐手道. It's 당수도 in Korean Hangul. It can also be romanized as “Tangsudo” or “Dangsudo.”
