Humble android bundle 4 problems

Hello steam gifts ,i recently bought the humble android bundle 4 and i downloaded all those apk files on my pc the transfered them on my phone(note that i dont have an internet connection on my phone yet,also i dont have a wireless router) ok so i go in the folder where i downloaded them and tryed to install but guess what its says"aplication not installed" so yeah i really need help (also note thet i dont have an sd card i use my internal memory of 8 gb) also another strange thing aperantly i installed eufloria and i thought onlyt it could be installed out of all and then i tried all of them and no other would work ...mins later i tried again another cobalt which i downloaded from a wireless conection (which at start when it was barely done downloading didnt work) and it worked and now i try to install other apss and again it doesnt work ...help
