I want to modify sched.h to add in some scheduling algorithm. I use find / -name sched.h command finding a lot of results.But which one should I really modify ?
And in /usr/src,there are a lot of relating folders whose names are similiar. I'm using ubuntu14.04. Where are my real source code?
use uname -a to see which kernel you are currently running. After that, i would edit the /include/linux/sched.h for that kernel.

I would like to know how to use grub and what it is used for. I would also like to know if I can boot freebsd and linux with grub. I have googled it but couldn't find much
grub is a bootloader that allows you to boot multiple distros and or kernels. Your motherboard should allow you to boot multiple partitions.

What command line would give me a list of programs each logged in user is executing for a Linux server using bash?
You can use the w command for this.
As #ivanivan mentioned, a more complete listing can be accomplished using ps, usually coupled with grep to filter out what you don't want.

How I can find out how much /tmp space is required by an application. Generally sometime I see /tmp is full and get error saying not able to write to /tmp. So is there any way to find out how much /tmp space is required by an application ?
There is no way. Programs use /tmp on an ad-hoc basis.

I'm trying to make files in my linux virtual server browsable from my windows. I'm following the instructions given here: https://help.ubuntu.com/lts/serverguide/samba-fileserver.html
However, I cannot find the security parameter it's talking about. Can I just create that anywhere under the [global]? Or is there a pretty specific place to put it?
Yep, you can just specify the "security=" parameter anywhere in the global section.

I am using Ubuntu 12.04, and I used to see #include , I want to see the implementation code of sys/stat.h. But I don not know where it is. By the way, I can not find it in /usr/include directory.
on my machine there are
/usr/include/x86_64-linux-gnu/sys/stat.h
/usr/lib/syslinux/com32/include/sys/stat.h
I think the first one is what you are looking for? it comes with gnu gcc I think
