Here's the one on the right: https://www.kenrockwell.com/tech/industar/55mm-f28.htm

The Helios 44M 58/2 in the middle is a classic and you can discover all the info you need about it via google searches. Uses an M42 screw-in mount; adapters are readily available.

The one on the left also uses M42 mount; here's some info: https://vintage-camera-lenses.com/carl-zeiss-jena-biometar-80mm-2-8/
