Can you Combine two script together?

Hey I need little help, this just a change team script, here is two script I need to combine

function Click(mouse) 
if script.Parent.Parent.Parent.Parent.Parent.Parent:IsInGroup(0) and script.Parent.Parent.Parent.Parent.Parent.Parent:GetRankInGroup(0) >= 1 then 
script.Parent.Parent.Parent.Parent.Parent.Parent.TeamColor = BrickColor.new("Bright blue") 
end 
end 

script.Parent.MouseButton1Click:connect(Click)

and this one

function onButtonClicked()
script.Parent.Parent.Parent.Parent.Parent.Parent.Character.Humanoid.Health = 0
end

script.Parent.MouseButton1Click:connect(onButtonClicked)

and can you fix this script only change health player to 0 when player in group

function Click(mouse) 
if script.Parent.Parent.Parent.Parent.Parent.Parent:IsInGroup(0) and script.Parent.Parent.Parent.Parent.Parent.Parent:GetRankInGroup(0) >= 1 then 
script.Parent.Parent.Parent.Parent.Parent.Parent.TeamColor = BrickColor.new("Bright blue") 
script.Parent.Parent.Parent.Parent.Parent.Parent.Character.Humanoid.Health = 0 -- Just add it to the bottom of the function!
end 
end 

script.Parent.MouseButton1Click:connect(Click)
