Trying to do some research on this... you're at least partially right: Kosuga, Uemu, and Moruta were all introduced at the same show; however, only Kosuga and Uemu actually performed, indicating that they joined HPK some time before Murota; so they could be considered different generations.

Okamura was introduced in June, but looking on Japanese Wikipedia it says she joined in March (the same month Murota joined); it cites Hello! Channel as the source for this, and I can't find visual proof of it, but if it's true, then Okamura and Murota could be considered the same generation because they both joined in March.

...Kenshuusei history is confusing...
