Can I change the language of my photoshop? spanish to english?

It is.

First step: install the English language version via the Creative Cloud Desktop app.

Next: In Photoshop Preferences > Interface > UI Language, English will now be in the drop-down menu. Select it, and restart Photoshop. (It might be already there, you may want to check first).

If not, here's a step by step with screenshots. Photoshop CC / Wrong UI language / How to change? | Adobe Community
