High-rise cladding combustibility tests have been carried out across the UK in the wake of the Grenfell Tower fire.
The fire service said those which failed in West Yorkshire were a mix of privately-owned buildings and social housing - all six storeys or higher.
The West Yorkshire tower blocks which failed cladding combustibility tests are:
Some of the failed tower blocks have been asked to install temporary fire alarms, move smoking areas and clear rubbish and combustible items.
PPHE Group, which runs Park Plaza, said the hotel "proactively" submitted cladding test samples and "fully complied" with the fire service's interim requirements.
Shaun Broers from Park Plaza said: "At this time no recommendations have been made to remove or update the cladding.
"This will be reviewed if any further guidance or advice is offered from the Department for Communities and Local Government."
A spokesperson for Unite, which manages Concept Place and Sky Plaza student accommodation in Leeds, said: "Based on the advice of experts and bearing in mind the wide range of fire prevention measures we have in place, we believe our buildings are safe for occupation.
"We will do everything necessary to ensure our buildings remain safe."
The fire service said more fire engines would be sent to tower block fires; six (one with high-reach capability) to most tower blocks, and eight (two with high reach capability) to failed blocks.
Residents were also urged to "do their bit" in being vigilant and knowing evacuation procedures.

He stood down from his role earlier this year because of ill health but was to officially remain in post until February 2017.
Mr Murphy played football and hurling for clubs in Down and was a county selector in the early 1990s.
A lengthy career in administration included being a former member of the GAA Central Council and vice-president of the GAA.
Mr Murphy served as vice-president and president of the Ulster Council before being appointed provincial secretary, a position he held for 16 years.
"Danny was an outstanding leader who provided unstinting dedication to the GAA in Ulster for over 35 years," said Ulster GAA President Michael Hasson.
"It was very fitting that Danny's leadership was honoured earlier this year by the First Minister, Arlene Foster, and Deputy First Minister, Martin McGuinness, at Stormont in recognition of his efforts in promoting reconciliation, tolerance and respect across all communities.''
Mr Murphy's funeral mass will take place on Saturday, 10 December in St Mary's Church, Burren.
