Is it normal that i want to kiss people on the lips...

No.

You shouldn't try it, you'd most likely freak your friends out. It's normal to want to be affectionate with people you love... But there's always a limit haha

I do this ?

Normal, but sadly uncommon. You need to make real sure that your friends understand what it means and what it doesn't mean for you. But once they do, and are ok with it - it's probably something you could start doing.

I'm a girl and I have this urges too,but mine is limited to hot girlfriends who I really like ,but I'm carefully nowadays coz many infections can be spread this way

Some people are lip kissers, some are cheek kissers, and some are huggers. Of course there are combinations of these as well. Know your boundaries, with friends and families and it'll be all good!

It depends on the friend. I kiss some of my friends on the lips, both male and female. I wouldn't do it with all of them but some are very kissable.

yeah, i have often wanted to do this as well, but could someone please tell me how to do this so they dont take it the wrong way (im a girl btw)

In some cultures, it's considered regular greetings.
