Icons & images usage Inquiry

I am planning to design & upload ui kits on themeforest also planning for flyers posters upload on graphicriver but i am confused in licencing of icons and images which i use in preview and add as a dummy in my kits and templates like icons from iconify plugin which uses MIT License, which allows for commercial use without requiring attribution,Feather Icons are licensed under the MIT License, which permits free commercial use, including in UI kits and marketing materials, without the need for attribution​,material icons (These icons are licensed under the Apache 2.0 License, which also allows for commercial use. You can modify and use the icons in your projects, provided you include a copy of the Apache License and avoid using the icons in any way that suggests endorsement by the creators​),iconsax * Iconsax follows a Creative Commons Attribution 4.0 license. This means that you can use the icons freely in both personal and commercial projects, but you are required to provide proper attribution to the creators. and hero icons uses mit licence,images from freepik free images,unsplash,pexels,pixabay etc free images royalty free not premium just dummy free fonts, Also i will give and link to each font image and icons i used in my kits and templates. Please guide me in this regard.
