pipeline datapath and instruction dependency

I am asked to identify the dependencies between these instructions for a pipelined datapath

I can see that there's 3 dependencies here..

instruction in line 2 & 3
instruction in line 4 & 5
instruction in line 9 & 10

assuming that we number the instructions from 1 at the start of the line... is this true?

I assume dependencies in pipelined datapaths means the second instruction has to wait for the first to finish?
What does line 6 do?  Is it dependendent on what happens in line 5?

How about the BNE instruction - doesn't it depend on the contents of the registers?

well yes it depends on the register $4 and $0, but those two registers don't cause a problem

also the add and the sw doesn't seem to create a hazard as there is forwarding in the pipeline architecture
