You should get two BMS. One for each battery.

The amps depends on the cell ratings AND the planned loads.

You previous post discussed a 48 volt system , did you mean series or parellel connection of the 24 volt batteries?

I think that there's some information missing, here.
If you have purchased pre-made batteries. They should already have a BMS built-in.

I was thinking about 48 v but decided to go with 24 v and running 2 24v in parallel

I plan on building my own batteries

What was your reasoning to choose 24V over 48V?

24V is kind of a no mans land between an RV system and a home based system. With 48V, everything runs at half the amps so all the wiring, connectors, fuses, yada yada yada can be smaller and usually cheaper.
