Can I post some of themes on my blog

hi there,

I would like to ask if I can post some of the free themes on my own blog, and I will the owner or author of those themes with the link to the original website.
In my blog, I’m going to explain such themes and integrate those themes into my own projects. So then I’m going to post my projects for the public for free.
Currently, I’m a student and I plan to make my own blog about programming, and how to teach people programming in a practical way.

I hope it will be no problem to use those free themes on my blog
Best Regards

Yes, you can do that.
