Need help installing smart switch with current Switch Panel

I have 3 switch panel and I want to replace switch 1 with TP-Link HS200 Smart switch



From left to right:
Switch 1: Controls the outside lights. There is only one switch no other switch in the house or garage controls the outside light.

Switch 2: Controls the chandelier. Behaves same as switch 1, no other switch in the house controls the chandelier.

Switch 3: Controls the hallway lights. There are two other switches in the hallway that controls the same lights.

I want to replace switch 1 with TP-Link HS200. However, there is one red wire coming from box it is wrapping around switch 1 then going to switch 2 and then to switch 3.



Now here is what I was thinking and need some expert advice as I am new to this:



if I can somehow manage to take the same red wire part that is connecting to switch 1, connect that to HS200 Black wire 1.
Yellow wire connect that to HS200 black wire 2
HS200 white wire to white wires connected in the box.

This switch box doesn't have ground wire and I checked other switches that control the hallway lights they also don't have ground wire. They just have a bunch of orange wires. Is it okay to leave the ground wire as is? I bought a small green color ground wire from home depot, but I don't where I should connect to in the box.
