Hey, welcome to bluelight.
Unfortunately absolutely nobody can tell you what you have from just about any descriptions you could give. Even if the pills you have happen to be really common presses, you still have no idea whether you have the real deal or a copy containing who knows what. You could have anything from pure MDMA, a similar RC like 5-MAPB, amphetamine, or even straight milk powder with absolutely ZERO active substances. The only safe ways to know what's in a pill or capsule you have is either to use a presumptive test kit that changes colour depending on what it's reacting to, or a laboratory GC/MS machine. Anything else like appearance, smell, taste, or even actual effect is not definitive and really just taking a guess. Even reagent test kits aren't 100%.
