Answer 1

you cannot reach your goal with 5 batch numbers, each individual receipt needs its own batch record , then you can do FIFO either based on the number (if internally assigned with GR, as then it is sequential) or based on the GR date that is stored in the batch record.
If you receive 2 goods receipts to the same batch, then you cannot know which part of the batch is the older one.
Better you use individual batches.
The meaning of your current 5 batches should become a batch characteristic. Then you can use batch determination to find only batches with a certain characteristic when you consume or sell the materials.
