1- Yes. You get share in all properties and cash.
Since you are brothers and three sisters, the inheritance is distributed to seven shares, three for girls and four for the two boys.
Percentage wise, 14.29% for each daughter, and 28.57% for each son.
Example,
If the parents left $ 1000,000.00, each son would inherit 285,714, and each daughter 142,857.
2- The same principal.
3- 14.143% for each daughter, 28.286% for the younger son, and 28.286% + 1% =29.286 for the eldest son.
4- No body has any wilayat on any one other than the father on his kids who are below boloogh, and daughters for marriage.
Hence, none of the brothers has wilayat on sisters, and you have the same rights in the inheritance, as explained above.
