A stealth aircraft looks to a radar a bit like a disco ball: its reflections are all specular and concentrated in specific directions. Except, unlike a disco ball, the mirrors are arranged such as not to hit the observer's eye as often, and are tinted dark by using RAM.
Here are a few: High bypass. Not all of the air that enters a turbofan engine's intake enters the actual combustion chamber. Bypass air helps to cool the hot combusted air before it exits, reducing the IR signature. The A-10, not a "stealth" aircraft in the slightest, nevertheless operates in situations where MANPADS (shoulder-fired SAMs) are a ...
What is in the 'stealth paint' that coats stealth bombers e.g B-2 spirit, and stealth aircraft, e.g SR-71, and how does it absorb/deflect radar?
5. Stealth aircraft include options to reduce visual signatures, so yes. This is achieved as a side effect of reducing the infra red signature, which is done by mixing the engine exhaust with environmental air before it is ejected, cooling the air a lot and thus making contrail generation far less likely.

Modern stealth aircraft such as F-22 and F-35 accept some possible dihedral corner reflection spots, but mitigate the effect by use of non reflective / absorptive materials. Epilogue: Modern civil radars do not need much of a return signal to spot a target, military radars even less so.
A stealth aircraft isn't actually invisible to radar. It's just harder for current radars to see stealthy aircraft at longer distances. This gives a stealthy aircraft the element of surprise against an enemy.
Many places in the world do not have primary radar coverage at all, meaning that if a transponder fails - stealth aircraft or not - it will disappear from the radar screen. Controllers will then revert to providing procedural (non-radar) separation, based on position reports transmitted by the pilot.
23. The sky in most of the world, most of the time, isn't blue. It's various shades of grey. A blue aircraft would stick out like a sore thumb against grey skies. This was found out already during WW2 when your thinking was applied by several nations to paint the bellies of their aircraft.
12. In Hephaestus Aetnaean's answer to this question, it is mentioned that the F-117 had no radar detection equipment because at the time it was developed the designers had not figured out how to integrate the antennas into the body without increasing its radar profile. How is this done on newer stealth aircraft?
FIrst, stealth does not make an aircraft invisible- it just makes them harder to detect. Stealth (or correctly, Very Low Observable (VLO)) aircraft can and are detected by radars and other surveillance mechanisms. Stealth aircraft are usually optimised for low observability in some radar frequency (mostly in Ku- and X- bands).
