Is the viltrox af 25mm f 1 7 air good for street photography?

Yes, I think it's a good street lens. The site's own street page says small and quiet beats megapixels, and this 25mm f/1.7 is light and cheap, with a fast aperture for low light and a field of view close to what you see with your own eyes. On APS-C it frames roughly like 38mm on full frame, which suits street scenes without being so wide that you have to get close to people.

For a small, quiet pairing, I'd look at the Fujifilm X-T30 II, the Nikon Z fc, or the Sony a6400. All are APS-C bodies this lens fits.

Remember that street photography depends on people, and rules about photographing them in public vary by country. Read the street page before you head out. For a bigger-picture view of sensors, see Sensor sizes.
