Both sentences are grammatically correct.
1). Originally, there are two sentences
"I am your friend". "I shall always help you."
When the two sentences are joined together by substituting the second "I" with the relative pronoun "who" as a conjunction, the verb (the auxilairy verb "am" functioning as the main verb) stays the same, thus:
"I , who am your friend, shall always help you."
2). Originally, there are two sentences.
"My brother is my best friend". "My brother is going to England to further his studies."
When the two sentences are joined together by omitting the repeating subject "my brother", the second verb "is" is omitted as well, thus:
"My brother and best friend is going to England to further his studies."
This sentence can also be written as:
"My brother, who is my best friend, is going to England to further his studies."
However if the author intends to mean his brother and his best friend are going
to England, he will need to say:
"My brother and my best friend are going to England to further their studies."

Thanks for the shocker. The expression did look weird, but luckily Ashley came to my rescue. The dictionaries did confirm that "further" is also a verb (meaning "to advance"), so "to further their studies" (which I've used all my life) seems okay.
