HTML > CSS > JavaScript > HTML5 > CSS3 > python > php > SQL > Java > C# > C++ > C

it really doesn't matter what order you learn them you just have to figure out what platform you want to master for example learning html is good for web. Java is good for Android platform while C is good for PC software. The only reason i give the list is based on Syntax. python has the most easy going Syntex while C, C++ and Other low level language are very syntax sensitive
