First you could start to use punctuation and separate your questions to make your post easier to read.

Then you could go here and read the page, you'll find the very basics about rpm there.

Basically you need to be root, and know 3 commands to start
installs an rpm package
upgrades an installed rpm package
removes an installed rpm package

After that you could go and read the rpm howto
It teaches you all you need to know and more about rpm.

all rpms want to glibc always says glibc xxx needed i want to learn glibc installation i extract glibc directory /usrlocal/src/glibc-xxx then make another directory because of it says seperate directory then i write ./configure it creates config.log but after i don't do anything what am i do after

One rule of thumb I always followed when I used rpm-based distros was to stick with rpm packages and never mess with source installs.

Go to rpmseek , download glibc and install it with the commands mentioned above.

If you mess around with glibc, you can end up with a system that doesn't work properly or programs that crash everytime you start them. Use YAST and install Suse packages instead of downloading them from third party download sites. Glibc should be already installed anyway, what you need is the development package and its usually named something like glibc-devel.

when i install rpm package it gives this error an i want to learn which package i download for example i386 i586 src or i686

This is best known as dependency hell.
You know reddazz is coorect, you should stick to using Suse packages and install them with yast.

If you really wanna learn about rpm, my advice would be to switch to Fedora since rpm (red hat package management) is theirs and Suse is not the most flexible distro around - but that's only my personal opinion.
Fedora has apt-get (Suse too I know but not nearly as developped) and apt-get facilitates installing software a LOT!
