I share a Windows laptop with my siblings, and I have the administrator account. The C: drive has only about 900 MB of free space left. My sister has Adobe Photoshop and Illustrator installed, but neither of us uses the other person's software. If I uninstall those programs from my account, will they be removed for every account on the laptop? Also, does installing a program for all users take more storage than installing it for just one user, and what are the best ways to free up space safely?

With only 900 MB free, uninstalling unused applications is a good start, but also check temporary files, downloads, large videos, and old update files. Move personal data to another drive or cloud storage if appropriate. If the laptop supports it, replacing or adding a larger SSD is a more lasting fix; be careful with cheap flash drives or microSD cards for important data.
Installing an app for all users usually saves space when multiple people need it. The main program files are installed once, while each account keeps its own settings and preferences. Installing separate copies for different accounts could use more storage, but the exact behavior depends on how the application's installer was designed. Some installers let you choose between the current user and all users.
Yes. If you uninstall Photoshop or Illustrator through Windows' installed-apps settings, the shared program files will generally be removed for every user on that computer. User-specific settings, documents, and preferences may remain in each person's profile, so those would need to be cleaned up separately if you want to recover every bit of space.
