Conclusion

Checks #1 and #2 probably come from one device: canvas, WebGL scene, WebGL, fonts, audio, graphics card and 16 more match. The IP address is the same too.

Checks #1 and #3 are partly alike (56%): WebGL scene, WebGL, fonts, graphics card, memory, voices and 8 more match.

Checks #4 and #5 match by 90%, but this may be another device of the same model: such devices (an iPhone, for example) share every rendering trait, and the system settings or voices differ.

• 98% #1 ↔ #2 probably one device match: canvas, WebGL scene, WebGL, fonts, audio, graphics card, screen, cores, time zone, memory, languages, platform, touch points, IP, WebGL scene 2.0, WebGL parameters, screen and frame, system settings, system sound, system voices, sound and video devices, emoji
• 90% #4 ↔ #5 alike as one model match: canvas, WebGL scene, WebGL, fonts, audio, graphics card, screen, cores, time zone, languages, platform, touch points, WebGL scene 2.0, WebGL parameters, screen and frame, system sound, sound and video devices, emoji
• 56% #1 ↔ #3 partly alike match: WebGL scene, WebGL, fonts, graphics card, memory, voices, touch points, WebGL scene 2.0, WebGL parameters, system settings, system sound, system voices, sound and video devices, emoji
• 55% #2 ↔ #3 partly alike match: WebGL scene, WebGL, fonts, graphics card, memory, touch points, WebGL scene 2.0, WebGL parameters, system settings, system sound, system voices, sound and video devices, emoji
• 14% #1 ↔ #4 different fingerprints match: system settings, time zone
• 14% #2 ↔ #4 different fingerprints match: system settings, time zone

All pairs (10)

• 8% #3 ↔ #4 different fingerprints match: system settings
• 5% #1 ↔ #5 different fingerprints match: time zone
• 5% #2 ↔ #5 different fingerprints match: time zone
• 0% #3 ↔ #5 different fingerprints nothing matches

The percentage is an estimate, not proof. Identical computers with the same graphics card, system and settings can match almost completely, and a browser with fingerprint protection (Brave, Tor Browser, Firefox with resistFingerprinting) changes canvas and audio every time.
