Girl do you use your energy to the band

ペコロス---is a kind of small onion [1]. I don't know if it has some additional meaning here, like the name of some popular figure, or a catchphrase.

The rest looks like: "Is everyone being a good [healthy] little band-girl?"

(breakdown)

皆さん...../ 元気---に ............../ バンドガール/ してます--か

everyone/ healthily+prep. prt./ "band girl..../ doing+interr. prt.

I have no idea what a "band girl" might be. I might be able to offer a more accurate translation if there were some context.

[EDIT]

@ Pixie Dust: a note on grammatical structure:

"元気に...します" the "に" here is not locative (prepositional "in"), but is required for the verb, making it adverbial, the way in which someone does an action. You can think of it here as the adverb suffix "~ly".

I'll have a go at this, but I'm not fluent.

Pekorosu (no idea what this means)

Everyone is dooing well in the bandgirl?

I don't really know what this means though, it could be written incorrectly.

Hope this helps :)

Looks like..

"Pekorosu!!"　←　Not sure if that's even a real word...

"Does everyone know the healthy band girl?"

I'm not perfect at Japanese, hopefully I didn't embarrass myself. But that's what it looks like to me.

Edit:

Sorry, I looked at it again...I think "Shitemasu" means "to do" ...Not "to know" ;;^^

Hopefully your next answers will be clearer.

ペコロス is a small onion.
