Can you guess KPop idols from Emojis?

Is the 1st one Leenalchi?

Who?

This one:

1) 🏰🗾

Is this a reference to Leenalchi or does it have to be an idol, not a group?

Leenalchi is a group.

Quote from JiminieKookie

I alreasy said 'Who', so... asking again about someone who's not even involved in here when I said 'who' ...

I guess you mean idols, not groups.

1) is an idol from Japan but I have no idea what the castle could relate to

2) I only know The8 so I am not sure if there is another number-named idol

3) pretty sure that's Lily!!!

4) Holland! The flag + tulips and cheese to represent the country

5) someone who's Australian, I would guess Felix because he has a cute face but then his voice is so deep

6) someone who also composes? Has a brother maybe? I will guess Zico because I read he has an idol brother and he produces music

I hope I got at least 3 and 4 right
