How to select more items and change the font for al the selected items?

[Anne5CF5]

I have several text boxes for the numbers for a calendar. Can I select them all at once and give them a different font?

Yes, if you want to change them all to the same font, use Character Styles: https://helpx.adobe.com/photoshop/using/formatting-characters.html

If you had used Charater Sytles much like InDesign, yes. You could just go in and change the Character Style to a new font and every place that you used that Character Style would automatically change. If not, I suppose you could shift click to select all the text layers and change them that way, but you could run into problems. I would create a Character Style, apply to each one quickly, then change the style.
