is 怒って (okotte) the common way to say angry in Japanese?
for example, "I am angry!" "Okotte da yo!" "Who is angry?" "Dare ga okotte desu ka?"

side note: I find it very interesting that the kanji had "woman" and "heart" for "angry." Maybe anger is weak, so they have a weak "female" heart?

Answer

怒っている = I'm angry
怒った = I got angry. / I am angry
怒る = get angry.

The radical at the top means "guy".
The radical at the bottom means "heart/mind".

Why do you assume that female is weak?

Answer

"I am angry!" "Okotte da yo!" →”おこってるよ！”
"Who is angry?" "Dare ga okotte desu ka?" →”誰がおこっているんですか？”

Answer

you can express your anger a few other ways too, 
for example.
もう、腹が立った　（はらがたった）　or　腹が立っているのよ　（Im angry, Im pissed off)

or 頭にきたよ　（あたまにきた）　that (or, you)　shits me to tears.(makes me angry/upset)
or 最悪！　（さいあく）　said with serious frustration or anger in your voice, it means...　this, or , you, is the worst.

enjoy getting angry.
