Do any of these have a paid option too?

Some do — several landmarks below have a real guided-tour or skip-the-line option linked alongside, for anyone who wants a paid, guided version of the same free sight.

What's the best time of day to visit for free?

Early morning or just before sunset generally means smaller crowds at outdoor landmarks — indoor sights with free entry days should be checked directly for opening hours.

Is Boulder walkable between these spots?

That depends how spread out they are — check each landmark's real coordinates on the map below, or consider a hop-on hop-off bus if they're far apart.
