In the case of multiple roommates, if one roommate moves out and another moves in then it's likely the "new" roommate is not on the lease agreement, and their eligibility has not been reviewed.
As far as what a landlord is required to do it is best to consult your attorney, but the TREC leases list specific names of people that are allowed to live on the premises.

If both sides are agreeing to new terms (ie, a new tenant), then likely there could be other changes to the lease contract. If the tenants (new and old) don't agree to the raise in rent or the new lease terms, the owner might not agree to allow the new tenant to move in. Key is both sides need to agree.
It will depend a great deal on the lease terms in their signed lease contract. As always, we recommend those with legal questions seek help from a real estate attorney as Realtors cannot give legal advise.
