I'm not 100% sure about the names of the flowers so I did not even try to guess or claim to know anything.
You can use these photos according to the rules of Stock Images community.
Also you can use these photos anywhere else you choose to use them with the license CC BY.
Read more about it here: https://creativecommons.org/licenses/by/4.0/deed.en
That means that you can also use them in your art: remix (cut copy paste alter) the images, but you have to mention me, the original photographer: Insaneworks and link at least one of these following sites or this post.

If you choose to remix any of the photos, it would be nice if you provided a link to this post next to your own work, although that's not absolutely necessary. You can also just use any of the generic links.

More purple.
Stump makes a perfect background.
White picket fence. Peekaboo!
Tiny tower.
Calm.
P.S.
You also have my permission to use the photos in this: @insaneworks/flowers-flowers-flowers post as Hive stock images. I didn't remember to include that post to the stock images community when I wrote it and I don't want to change the tittle now, 22 days later. But same rules apply as in this post. I'll include the hivestockimages tag to that post and add a P.S. text to the end of the post to make things more clear.
Edit day after:
I almost forgot this rose couple.
