Ok, I've managed to do it with a little help from chatGPT :D 

Here are the steps:

1. After importing the folder with fbx to UE5 there will be also a material created called "FantasyArena2_02"
2. Double click on the material.
3. In the editor right click on empty space and choose adding "TextureObject"
4. Drag the png combined texture you've downloaded onto "Texture" property in details panel of the TextureObject node.
5. In the editor right click on empty space and choose adding "TextureSample"
6. Add link between the TextureObject and "Tex" in TextureSample
7. Add link between "RGBA" on the TextureSample and "BaseColor" on the "FantasyArena2_01" which is already present in the material editor
8. Wait a bit and click "Apply" in the material editor (up&left), then click "Save"
9. You now have your material ready.
10. Add whatever object from the downloaded package into the scene.
11. Drag material onto the object.
12. Your object should now be colored correctly! :)

Hope it helps anybody using this asset pack :)
