Is any way to send data to others users?
You will need to be a little more specific. Other users of what? Your game, this forum, crack heads?
Without know what type of data you are trying to send and to whom, it makes it'a bit difficult to help.
hm, sorry for my bad english and obscure ask. I want to let game users to send gift to other users. For example, when user send gift, other user should get value, who let receive gift.. hm, something like facebook game "tetris battle".

Top of my mind , you'll need a server , and your C2 app to send messages to other people using the websocket plugin , I saw a tutorial on building one no a long time ago , by SGCONFI
