Hi @noelle,
I hope you are well today and thank you for your questions.
1- I wish I could change the “Theme by…” and add my own copyright and license, but I can not see how I can do without installing the child-theme.
You can try removing default copyright text by adding the following CSS code in the Custom CSS option of your theme on the below path.
Admin Area -> Appearance -> Customize -> Shapely Options -> Other
.footer-credits {
display: none;
}
Then add your own as described in the following topic.

2- How can I do to delete the title “Project type: News” on News page. I was able to delete double titles in other pages but can’t get it here.
Use below CSS code as described above to achieve this.
.tax-jetpack-portfolio-type.term-news header.page-header {
display: none;
}
3- I also like to know if you can add to this page a side bar like a blog archives but associated with the projects.
You can display the default sidebar on that page and then change it to another dynamic sidebar using the below plugin having widgets related to projects.
Best Regards,
Movin
