Vlan B 192.168.2.x/24
Vlan C 192.168.3.x/24
Vlan D 192.168.4.x/24

Vlan A is a public server vlan i want all the vlans to talk to Vlan A but vlan B c and D should not talk to each other.Can somebody tell me how to configure access list so that vlans B C and D dont talk to eachother.

On the layer3 device where the inter-VLAN routing is occurring, you need to configure access lists and apply them to the VLAN interfaces.

The access lists go

source_subnet destination_subnet allow
deny everything else
