1) Is there legal way to claim my share from my elder brother (A1) 10 acres land?
Though this property was purchased by your father A, it was bought on the name of your brother A1, hence he is the absolute owner of the property and only he has full rights over the property. Just because you had maintained the property for 20 years, you cannot claim ownership or title or even a share out of it.
2) Is binding of minor brother separate property in family arrangement is legally accepted?
This binding is not known how this was made, however in the absence of any registered document or deed, such bindings are not tenable in law.
3) Is limitation act restrict me to file suit to claim my father share from grandfather property and get back his 10 acres land given to uncle F
If your father has not transferred his share to his brother legally, i.e., by a registered document, you can very well file a partition suit seeking a share out of it, let the court decide about its maintainability based on the defence your uncle may adopt. Partition suit is not barred by limitation.
4) Am I have right to cancel/terminate family arrangement and file partition suit against my uncles?
Family settlement and arrangement or even oral partition among the share holders are generally not disputable in law especially if subsequently there was a mutation of records to prove individual possession out of such arrangements. However a civil suit's summons may create a stir and chances for a negotiation among others so that you can be benefited.
