A wetsuit will not protect you from the barb of a stingray, as it will go straight through the neoprene of the wetsuit and into your skin. But stingrays very rarely attack people unless they are provoked or threatened, so wetsuit or no wetsuit, you are unlikely to be attacked by a stingray.

Wetsuits do protect you from the sun as the wetsuit’s neoprene creates a layer and a barrier over your skin to stop the sun’s harmful ultra violet light rays from damaging your skin, as well as keeping you warm. To get complete protection from the sun using a wetsuit it needs to be a full wetsuit.
You do need a wetsuit to dive in the Red Sea, especially when diving in deeper waters and if you dive from a Red Sea liveaboard. You may experience cooler thermoclines in the Red Sea and depending on the time of year you dive and the depth, you will probably need a 1-5mm wetsuit.

If you run out of air while scuba diving, you should turn to your dive buddy and use their alternate air source (or octopus air supply), buddy breath and ascend. If your buddy isn’t close enough for buddy breathing, your alternative is an emergency ascent, unless you have a redundant air source.
There are four Philippines liveaboards with sidemount diving, which means that if you prefer to carry your dive tanks at your sides instead of on your back, or use smaller tanks to reduce the weight of your dive equipment, you can do this with these liveaboards.
