Most of them yes, they tell you in the description if it is melee attack only.
It looks like the only 3 that are limited to melee only are lunging attack, riposte, and sweeping attack.
Now some are only usable in melee range like feint and parry, they do not require you to be armed with a melee weapon.
Edit: wanted to add this does mean you can knock a flying creature of large size or smaller out of the sky with a blowgun dart if you wanted, I think this is cool and fun, I think some people have issues with stuff like that but I don't have any issues with using my imagination when it comes to stuff like that, it probably has something to do with all the Hercules and Xena I watched growing up.
