I have this type of washing machine faucet/tap in my apartment. Any idea how to remove the handle? There isnt any screw on top(after removal of the sticker), by the side, or back of the handle.
Is there special tool to unlock the valve handle?

From my point of view (image is very small and poorly illuminated) you face a hexagonal ending of the shaft, when looking at the top of the tap. My first try was to get a wrench socket, which fits the hexagonal stub. It may be difficult to find a matching wrench socket small enough to fit into the housing of the tap, but you could take a cheap one and grind the outer diameter down until it fits. then you screw it down with a matching screw and insert a short t-handle. Alternatively you may fix a valve handle to it via a sqare axis reaching from your wrench socket into the handle.
Update there's another way to make place for a wrench socket (assuming there's a wrench socket fitting the hexagon, but not the inner diameter). You could saw off the upper rim of the tap surrounding the hexagonal stub of the shaft, so you can place the wrench socket on it, without having to grind its outer diameter down, which is undoubtedly the harder work to do. The wrench socket — again — can be fixated by a matching screw and some washers on the tap to prevent it from popping out.
I drew a small black circle around the area of that tab where you can slip a utility knife point underneath of it and pop it out it should come out pretty easily.

Check to see if there is a nut just below the handle which the stem comes out of. If this is a laundry faucet or the type that projects from a wall there may be a connecting nut that allows the faucet to swivel into alignment with the supply pipe. Either way use a crescent (adjustable jaw) wrench or as @bib mentioned tape or a rag to protect the faucet from being marred.
