Rather sad to hear of the short time it took for the siblings to be at each other’s throats over the spoils. Too bad mother didn’t leave the home to a worthy charity instead of her scrapping children.
Be that as it may, if you want to do something to counter the Personal Representatives action in leasing the residence, then hire an attorney. You thus might be able to proceed under the Texas Probate Code * for his removal due to mismanagement of the estate and the appointment of a successor.
"Mismanagement" that might lie in the fact that he exceeded his statutory authority under that Code in leasing the property. The PR is charged with preserving the estate not encumbering them by debt or long term possession rights.
Also, it would be disastrous were the home to be distributed out of probate in equal undivided ownership by the 5 devisees, with each have equal rights of possession and the inability to sell the property without mutual written consent.
The heirs should consent that it be sold out of probate and the net proceeds distributed rather the home itself.
Talk to the attorney. There is nothing you can do without one
Also discuss with the attorney the heirs’ inchoate title to the home conferred upon them immediately upon the death of the testatrix. Inchoate title means that the heirs receive the legal title to real property subject to only the administration of the estate. Which I would argue prevents the PR from committing it to any but a short term rental and only where shown necessary to fund the expenses of administration.

[*] Grounds for removal of personal representative:
Texas Probate Code Chapter VII, Part 1 Section 222 Removal of Personal Representative Subsection (2)(b)(4)
“The personal representative is proved to be guilty of mismanagement in the performance of the personal representative’s duties.”
PART 5. GENERAL POWERS OF PERSONAL REPRESENTATIVES
"Sec. 230. CARE OF PROPERTY OF ESTATES. The executor or administrator shall take care of the property of the estate of his testator or intestate as a prudent man would take of his own property, and if there be any buildings belonging to the estate, he shall keep the same in good repair, extraordinary casualties excepted, unless directed not to do so by an order of the court."
And I see nothing in Sec. 234. “EXERCISE OF POWERS WITH AND WITHOUT COURT ORDER” that specifically empowers the PR to lease real property.
