1. Once i go get my L1B stamped then, will my H1B gets invalidated?

You can have multiple non-immigrant visas at one time from different employers, so the answer is NO.

2. If both can coexists, if i travel on L1B visa then if want to switch to employer B who sponsored my H1B, on H1B status then is it possible, while i am in USA?

Yes, you'll have to go through COS process

3. What are the general problems i may face in these situations?

Nothing as I could see. On the other hand you may ask company "A" to transfer your H1B visa, instead of applying for L1B for you.
