What is the best plan for me to start with T-Mobile to take advantage of free lines if I would eventually like to get to 4 or 5 lines total.
T-mobile Magenta plan would be best. Start with 3 lines so you get the 3rd line free.

I forgot the exact names but back in 2017, they had line on us, 2 lines on us for 20, line on us 2, I believe. So they apply across all lines any lines removed you lose the free lines. Not worth the chance at least in my case.
The older free lines, you only had to keep the existing paid lines, not future ones added after those free ones.

You are correct, your plan only allows up to 3 lines.

If you have kickback and a dual sim phone, you can guarantee always getting the kickback discount. That is my current setup on 2 iPhones so I receive a $20 savings each month.
Since the free line doesn't get kickbacks is your setup to be able to use the data from the free line and stay under 2 GB for the paid lines. I might need to look into this, I never knew about dual SIM. I'm assuming iPhone 12 Pro Max has the capability?

I gave my current FREE line to my nephew to use but I've always been on the fence about changing plans just to add another FREE line because I really had no need for it. I'll need to see if changing plans will even be financially beneficial.

My GV number worked, I signed up the GV number literally couple of days before porting in, just received my GV port-in for the $100 promo from T-Mobile and used it on my bill today, I guess it depends on what service provider was used on the GV number?

Newer iPhone should support eSim. For some reason TMO doesn't allow with Samsung phones.

Yea. Both phones iPhones. Setup is so that data is used from the free line. Don't have to worry about my data usage from that line because line is free. Paid line data usage is then alway under 2gbs to receive kickback because it's not being used.

You should definitely do so if you can. Can only save you money. No real downside.
