That is better @abanksforever but still not good enough.

When you use wikimedia images, wikimedia provides specific format for attribution.

For your first image the details of the format is given at WikiIMage. On this page click "Use this file on the web" link to get the details.

When you use their format for attribution, your attribution would be displayed like this:

_{Светлана Бекетова, CC BY-SA 3.0 GFDL, via Wikimedia Commons}

In this attribution format the source and the license details are linked and found on the same page. When your readers click on the link provided in the attribution, it takes them to the above referred WikiIMage page with full details of the license. Your readers do not have to go elsewhere to check the authenticity of your right to use it and may use it themselves with confidence if they wish to.

I hope from now on you can follow this procedure for wikimedia images.

As for your third image your source doesn't link it to the license details and you have also not provided the license details. Upon checking I found its license details here https://www.flickr.com/photos/johnseb/7523387820/in/photostream/. From the details provided it is clear that the copyright holder wants you provide appropriate credit to him and provide a link to the license. That means, to comply with best practices, you could have formatted as follows:

_{"European Footballer of the Year award" by John Seb Barber licensed under CC BY 2.0}

As for the fourth image, it is not clear from the source cited by you whether the image in fact carry the license you have linked it to. Your readers would never be sure whether the license you have provided is in fact the actual license.
