How do you say "Who is this?" or "Who is that?" in Japanese?

How to say these things in Japanese?

• Okay, could anyone tell me how to say (in romaji and Japanese characters, please): -I don't know what to say! -Whoa, that was too much for me to say. -I don't speak Japanese very well. -I'm from America. -I'm just going to say random things now. -Hi! Nice to meet you. -Goodbye, everyone. -I love you guys/ya'll. -These lyrics are crazy/random/weird. -I'm still learning Japanese, so please excuse my horrible usage of it. -My best friends are xxx -I love this song. -This is really hard (to say, to do, to be) And finally... -Yay, I'm done the song! Yes yes, I know some of this stuff is pretty random. But my friend and I are planning to do our vlog from Japan in June and we NEED to know these things. Her mom is Japanese but is too busy to tutor us and she (my friend) knew it when she was little, but forgot >:P Thank you! <3

  -I don't know what to say! 何て言えば良いか分からない！(Nante-ie-ba-iika-wakarana… -Whoa, that was too much for me to say. すみません！分からないです。(Sumimasen-wakaranai-desu) -I don't speak Japanese very well. 日本語をうまく話せません。(Nihongo-wo-umaku-hanase-ma… -I'm from America. アメリカから来ました。(Ah-meh-rika-kara-kimashita) -I'm just going to say random things now. すこし話がそれます！(Suko-she-hanashe-ga-so-reh-ma… -Hi! Nice to meet you. こんにちは！初めまして！(Kon-ni-chiwa-hajimeh-ma-she… -Goodbye, everyone. みなさんさようなら！(Me-nah-san-sa-yo-ooh-nara) -I love you guys/ya'll. みんなが大好きです。(Min-nah-ga-die-suki-desu) -These lyrics are crazy/random/weird. この曲の歌詞は不思議ですね。(Kono-kyokooh-no-kashi-wa-… -I'm still learning Japanese, so please excuse my horrible usage of it. まだ日本語は練習中なので間違っているかもしれません！　(Ma-da-nihon-… -My best friends are xxx 親友はXXXです。 (Sheen-you-wa-XXX-dehsu) -I love this song. この曲が大好きです。(Kono-kyo-koo-ga-die-suki-dehs… -This is really hard (to say, to do, to be) いいにくいです。(E-E-nikui-desu) これはとても難しいです。(Koreh-wa-totemo-muzuka-she-… -Yay, I'm done with the song! やった！この曲で終わりです。(Yattah-koh-no-kyoku-de-oh… Sorry if it's hard to say but if you really don't know how to pronounce it then Google translator has a read aloud button so that might be some help. Don't worry, I didn't use Google Translator! I'm Japanese! Good luck!
