Ok, let me try my hand at this.
First sentence is something like this being her first birthday live in her 10 years in show business.
Then second sentence is about all the fans making her happy.
Third sentence is saying that the commemorative first photo of her blog is together with all the fans.
then, "Thank you to all the fans that came <3"
"As a surprise, Yasuda Kei-chan and Miyoshi Erika-chan came too!! Thank you very much <3"
"I'm super-duper HAPPY <3<3<3<3<3<3<3<3<3<3"
Since this seems like it's written from a phone, the entries are short and simple, and shouldn't be too hard to translate for whoever wants to do so.
