In speech, these are pronounced the exact same.

heys thanks for the clarification =)

anyways i was wondering if its acceptable to use 上げる when someone gives something to my family member, or must it be in くれる e.g:
(1) ボブは妹にプレゼントを上げた
(2) ボブは妹にプレゼントをくれた

also, i came across this sentence 友達が私に教えてくれた。
From what i know, this sentence means “friend gave me favour of teaching me”. How do i modify it along the lines of “friend gave my father favour of teaching me (i mean something like the friend still teaches me, but the favour is not for me, its for my father)”. My attempt is this: 友達が父に私に教えてくれた but it feels very odd.

I sure wouldn't use あげる. I would use くれる／くださる. Unless for some reason my sister wasn't in my in-group (perhaps an estranged sister or something). My sense is that あげる is when a gift is moving away from me even further. くれる is when it is moving toward me.

I forget if you're a native English speaker. I think you are, right? It's chryuop who is Italian but living in the US. Regardless, I don't understand your English here.

友達が私に教えてくれた means "My friend taught me." More "literally/explicitly," "My friend [did for me] teaching."

If you mean "My friend taught me for my father's sake," I've never tried such a convoluted expression in Japanese, but I think I'd have a go with (say I'm talking to my mother) 友達がお父さんのために私に教えてくれた。

This google search ("のために教えてくれた" - Google Search) seems to suggest that 〜のために〜てくれる is permissible.

A few sample snippets I found:
"仕事のために教えてくれたことがあった。" <-seems to indicate you can structure it like I suggested
"オペラをやる仲間集めのために教えてくれたようです� �，..."
"主のために教えてくれたことなんだし。"
"片付け素人の私 一つ一つ手探りで 一歩一歩ゆっくりだけど前に進む自分のために 家族のために教えてくれた「 りゅうのすけ」のために"
"リスナーさんのために教えてくれた丸ちゃん"

does that mean that if i gave my sister a present, using くれる is not allowed?

yepp i am, sry if i wasn't clear.

does てくれる give the "I'm doing you a favour / i'm helping you out" implication? is it true that 私に教えた means "he taught me (fullstop)" while 私に教えてくれた means "he taught me (for my benefit)"

in other words will this sentence 友達がお父さんのために私に教えてくれた mean "for my father's sake, my friend taught me (for my benefit)"? if i were to say "for my father's sake, my friend taught me" will this be fine: 友達がお父さんのために私に教えた

[Edit]
or is it that てくれる does not have the "I'm doing you a favour / i'm helping you out" implication. and 私に教えてくれた means "he taught me (fullstop)" while 私に教えた means the same thing, but if we were to say 私に教えた it sounds awkward?

That sure would sound weird to me. Go with あげる. If you're feeling particularly misogynistic, use やる

Yes. All the て[give] verbs mean the verb was done as a gift/for someone/for their benefit/etc. てさしあげる、てあげる、てやる、てくださる、てくれ る、てもらう、ていただく.

I don't know the answer to that one. I have my guess, but I'll let someone whose Japanese is better than mine answer this one.
