1. Is it just like ubuntu I mean if i install an app thats for ubuntu will it run and work just the same?
It
IS Ubuntu. Literally the only difference is that it comes with LXDE installed instead of Unity or Gnome.
And literally the only differences between Lubuntu/Ubuntu and
the three hundred or so other distributions is that Ubuntu is based on Debian (and so uses Apt instead of some other package manager - many others use either RPM or something else) and uses slightly different names for virtually universal programs and libraries.
Anything that runs on Ubuntu
or any other distro will, more than likely, run on Lubuntu.
