Those are common XSS test payloads covering event handlers, SVG, iframe srcdoc, javascript: URLs, and <script> tags.
I won’t execute them here. If you’re testing an application, I can help you safely assess whether its HTML sanitization or Content Security Policy blocks these vectors, or review your sanitizer configuration.
