You don’t have any right on land as per your uncle will 

Was land in your uncle name 

if he was absolute owner of land he is at liberty to bequeath land as per his will 

If that property is belongs to ur father also .. then you will get equal share of the property ownership.. 

All owners will have sharing ration according the Built-up constructed flats/Building on the plot.

For e:g if its Stilt construction building of 3 Floors and all three floors has different owners than all owners will have shares in the plot area according to their flat sq ft ratio.

The first floor or the above floors did not come into existence on its own, if the ground floor occupant would like to demolish the ground floor then how can the occupants of the floors above will survive, hence the occupants of all the floors have a  right in the floor beneath the structure. 

Whether the testator had specifically mentioned about a share in the land beneath the structure to the occupants of the floor above ground floor or not, it is implied that occupants of first floor and above have equal rights in the land underneath 

A will is a legal document that expresses the wishes of a person regarding the distribution of his or her property after death. A will is valid only if it is made by a person who is of sound mind and free from undue influence, fraud or coercion. A will is also valid only if it is attested by two or more witnesses who are not beneficiaries under the will.

In your case, since your uncle’s will has given you and your brothers the first floor rooms and your cousins the ground floor and land, you have to respect his wishes and abide by his will. You do not have any right on the land unless your uncle has given you any such right in his will or by any other means. However, you have some rights as the first floor owner, such as:

• The right to use and enjoy your property without any interference or disturbance from your cousins or anyone else.
• The right to repair and maintain your property as per your needs and preferences.
• The right to access and exit your property through the common staircase, passage or road without any obstruction or hindrance from your cousins or anyone else.
• The right to claim a share in the common expenses and amenities such as water, electricity, security, etc., that are incurred for the benefit of the entire building.
• The right to seek partition of the building if you are not satisfied with the arrangement or if there is any dispute or conflict with your cousins or anyone else.

You have not been bequeathed any undivided share in land 

2) will is clear and unambiguous 

3) ground floor and land has been bequeathed to cousin only 

You are right in your understanding.

You are entitled to a share in the land underneath the structure.

If someone objects to tht you can file a suit for declaration of title to your entitled share in the  land underneath the building on the same logic and reason what you have discussed 

Sir/Madam,

You seems to be confused a bit. The intention of the testator is to avoid any confiict and that's why he gave right of land to other person and rooms at ...floor to other portion i.e.you. It does not mean that you may reach to proeperty in air. Rather, you may use the land in restricted way, i.e. parking, entrance etc. but cannot make any permanent construction.
