A single rollup command that does all this, no.

You construct what you need by combining the primitives together to get 
what you are looking for.

For size (if by 'size' you really mean the sum of the disk space 
consumed by the files inside the folder) then du with the --max-depth= 
(short form -d) option to prevent it from descending into sub-folders 
will give you the "disk used by all files inside".

du --max-depth=1 folder/

For count, there are several options.  If all the filenames inside are 
sane (as in do not themselves contain newlines) then this will give you 
the count:

ls folder/ | wc -l

If your filenames contain newlines, well, you've got a lot more work 
ahead....

If you really want a 'rollup' (because you use this often) you can 
create either a shell function or a shell script file somewhere on your 
path with a new name, i.e. size-count which does both of the above and 
then you can run:

size-count folder/

to get both the disk usage and files count.
