After you have downloaded the font go to your control panel, click fonts, and drag the font there and it will be put into photoshop.
this, or you can just download a font, then move it to C:\Windows\Fonts. it will install it then.
If you had photoshop opened during this process, you will have to restart photoshop in order to use it
