can somebody help me? how can I see my pics and info on Icloud

In Mac definitely a different Apple ID and password is signed in , using the same Mac , open a new tab ( use command and T keys ) , and sign in with Apple ID and password of your iPhone at www.icloud.com

The photos of iPhone can be viewed see this article https://support.apple.com/en-in/guide/icloud/mm73262d11fe/icloud

The iCloud data ( mails , notes , calendars .......etc ) can be viewed by clicking each application that is configured https://support.apple.com/en-sa/guide/icloud/mmb1de40d9/icloud read this article also https://support.apple.com/en-in/guide/icloud/mm281e3e7d/1.0/icloud/1.0

On an iPhone, iCloud is designed to be viewed by using the apps on the device (e.g., the Files app for iCloud Drive, the Photos app for iCloud Photos, the Notes app for notes, etc.).

You can also use an internet browser and log into icloud.com. What you can access via a browser varies by device. See: https://support.apple.com/en-us/HT210402

Also note that while you can view synced data as described above, it is not possible to view the contents of an iCloud Backup. You can only use the backup to do a full restore of a device or to setup a new device.
