Hello Nick,
Pretty difficult to say with these photos, specially the Rhinolophus of the end of the batch and the medium size Hipposideros.
The first Bat is Cynopterus, do you have any idea about the aprox size?
The second bats are Hipposideros cervinus
The third bats are Hipposideros diadema, both adult and juveniles
The last Bat IS a medium-small size Rhinolophus and i cant say anymore -

I was in this cave a few years ago as well, but didn’t take any picture unfortunately. But I found two other trip reports on this site [1, 2], which both mention Cynopterus sphinx, Hipposideros diadema, Hipposideros cervinus and Rhinolophus arcuatus to be found in this cave. Arcuatus I am not 100% sure, could also be intermediate horseshoe maybe?
For the other Hipposideros, could be intermediate roundleaf maybe [3].[1]: https://www.mammalwatching.com/wp-content/uploads/2016/08/Sumatran-Exploration-Sep-2014-MW.pdf

I am away so can’t take a look yet (and I am not super familiar with the bats on Sumatra) but the large spotted roundleaf bat is Hipposideros diadema.
