Are these sentences okay? Did I use "understood" correctly?
I called Shirley today but she did not answer her telephone so I left her a message informing her that our manager, Mr. Yong, wanted to speak to her again regarding the agreement she had signed as he wanted to make sure she understood the terms in the agreement.
There's only one sentence, so you have to write "Is this sentence okay?"
You used "understood" correctly.
The text would be easier to understand if you divided it into two or three sentences.
