function checksamount()
for _,snipers in pairs(workspace:GetChildren())do
        if snipers.Name == "Soldier3" and snipers:FindFirstChild("Owner") and snipers.Owner.Value == player then
            return #snipers
        end
    end
end

So from the for loop, I fetch the children of workspace. Then I filter all of the children through the if statement to get every object called soldier3. Now I end up with a variable with all of the soldier3's. How do I get the number of soldier3's in the variable?

From what I can tell, you're trying to find the number of instances in 'workspace' that meet the conditions in the if block. You can do this by using a local variable to count them.

function checksamount()
    local snipersNum = 0
    for _,snipers in pairs(workspace:GetChildren())do
            if snipers.Name == "Soldier3" and snipers:FindFirstChild("Owner") and snipers.Owner.Value == player then
            snipersNum = snipersNum + 1
        end
    end
    return snipersNum
end

Putting a return statement in the if block will end the function as soon as the condition is met by one of the children, even if the loop is not complete.

         if snipers.Name == "Soldier3" and snipers:FindFirstChild("Owner") and snipers.Owner.Value == player then
        local pat = "%d+"
         return  tonumber((snipers.Name):match(pat))
        end
    end
end

it uses a String Pattern to find the last numbers at the end and make them into a number. Goodluck :D
