Of course, they will !
If you want smaller in size, place you order on eBay, but in the mean time, those will do perfectly the job.

Thank you again

Can you give me another advice?

I need an alarm (buzzer), can this:

be powered through the esp8266?
it takes 3V and 20mA according to the datasheet.

I would recommend to drive it thru transistor/mosfet.
