How is the bond angle in graphite 120⁰(Trigonal planer)
Isn't the Carbon atom bonded to 3 other carbon atoms and isn't there a lone pair as deloalised electrons?
So isn't it 3 bond pairs and 1 lone pair which gives pyramidal shape w a bond angle less than 107⁰?

You've answered your own question without realising it. The fourth pair of electrons is delocalised so it isn't "attached" to any one atom, so it isn't repelling the other three. You might also recall from GCSE that graphite has a hexagonal layered structure, and the angles in a regular hexagon are 120⁰.
