If I have a thick layer of lip balms on my lips and kissed somebody with Herpes, do I get Herpes?

Yes, if they had a cold sore or fever blister at the time. Putting on a lot of lip balm doesn't prevent you from getting oral herpes which is what causes cold sores and fever blisters.
If they didn't have a break out at the time then you would only have a small chance of getting it.

Yes.
