You and the other children need to consult with an experienced probate litigator in Harris County (if that is where the estate is pending). An Independent Administrator is given all of the powers of an Independent Executor under the Texas Probate Code. That would include the power to sell assets in order to pay claims against the estate. The exception is real estate. He cannot sell real estate with a court order. He can be forced to provide an accounting of all transactions and assets.
DISCLAIMER: This is not specific legal advice and does not establish an attorney/client relationship.
Based on your description of what is going on, you need to consult with a local probate litigator to explore your circumstances in detail. Once you have consulted with a local attorney, you will have the necessary information to make an informed decision on how to move forward. If your uncle is not properly fulfilling his role as independent administrator, you can petition to have him removed and replaced. Good luck.
