how do you say, you (plural) in Japanese I know 皆 is everyone, but if I am just talking to a couple people and I want to say "you guys/girls" would it be あなたたち or is that to formal to say to friends?

How do you say "can you write that in hiragana/katakana?" in Japanese. For example, if someone sends me kanji, but I cant read it, I want them to write it in Hiragana/katakana. Thank you for your help!!
