Can I use same LDO for two outputs?
If the regulator provides enough current, then yes, it is possible to power multiple devices (or loads) from it. 

Let's assume you have a maximum of 10A available:

As you can see, it will easily power 3 separate loads. If the total added up to more than 10A, then you have a problem. Otherwise, it'll be fine.

This is the same for any regulator. Any voltage supply, LDO, SMPS or whatever you want to use that provides a voltage can supply multiple loads as long as you don't go over the maximum. 

Although saying that, it is always best to give yourself some headroom. If you have a 10A max, try not to go any higher than 9A for example, you will always get some unexpected resistances because the real world doesn't work in ideals.
